The most loaded element of the VAZ 2107 car is the front suspension. Indeed, it takes on almost all the mechanical loads that occur during movement. For this reason, it is important to pay careful attention to this unit, carry out repairs in a timely manner and refine it, as far as possible by installing more durable and functional elements.

Purpose and arrangement of the front suspension

Suspension is usually called a system of mechanisms that provide an elastic connection between the chassis and the wheels of the car. The main purpose of the node is to reduce the intensity of vibrations, shocks and shocks that occur during movement. The machine constantly experiences dynamic loads, especially when driving on poor quality roads and when transporting goods, i.e. in extreme conditions.

It is in the front that the suspension most often takes on shocks and shocks. By right, it is the most loaded part of the entire car. On the "seven" the front suspension is made better and more reliable than - the manufacturer, of course, took into account the high workload of the node, but this is not the only reason. On rear-wheel drive vehicles, the front suspension has fewer parts than the rear, so its installation is less expensive.

The scheme of the front suspension on the VAZ 2107 includes important details, without which the smooth movement of the car would be impossible.

1. Stabilizer bar or roll bar.
2. Double wishbone suspension - the main front suspension unit, consisting of an upper and lower independent arm. One of them is fixed with a long bolt through the mudguard strut, the other is bolted to the suspension cross member.
3. Ball bearings - are connected to the wheel hubs through the steering knuckle systems with the trunnion.
4. Wheel hubs.
5. Silent blocks or bushings - designed for free travel of levers. They have an elastic polyurethane (rubber) liner, which significantly softens the shocks of the suspension.
6. Depreciation system - includes springs, cups, hydraulic shock absorbers. Racks are used on VAZ 2107 models of the latest years of production and on tuned "sevens".

front beam

The task of the front beam is to stabilize the car passing turns. As you know, when maneuvering, centrifugal force arises, which can cause the car to roll over. To prevent this from happening, the designers came up with an anti-roll bar.

The main purpose of the part is to twist the opposite wheels of the VAZ 2107 using a torsion elastic element. The stabilizer is attached with clamps and rotating rubber bushings directly to the body. The rod is connected to the suspension elements through double levers and shock absorber struts or, as they are also called, bones.

Levers

The front levers are the guiding components of the chassis of the VAZ 2107. They provide a flexible connection and transmission of vibrations to the body.

The levers are directly connected to the wheels and the car body. It is customary to distinguish between both suspension arms of the "seven", since their replacement and repair are carried out in different ways:

• the upper levers are bolted, it is easier to remove them;
• the lower arms are screwed to the cross member connected to the spar, they are also connected to the ball joint and spring - their replacement is somewhat more complicated.

Front shock absorber

The owners of the VAZ 2107 learned about the existence of racks when the VAZ 2108 model appeared. From that time on, the manufacturer began to gradually install new mechanisms on the "sevens". In addition, the racks have been chosen by specialists carrying out the modernization of a classic car.

The strut is part of the damping system, whose task is to dampen the vertical vibrations of the body, taking on some of the shocks. From technical condition rack depends on the stability of the car on the road.

The front shock absorber strut includes several separate elements:

Spherical bearing

The ball joint is an element of the front suspension that provides a fairly rigid attachment of the lower arms to the hub of the machine. With these hinges, the car on the road is able to provide smooth movement and the necessary maneuvers. In addition, thanks to these details, the driver easily controls the wheels.

The ball joint consists of a pin with a ball, a thread and a body with a notch. A protective boot is provided on the finger, which is an important part of the element. Regular checking of ball anthers by the driver helps to avoid breakdowns - as soon as a crack is found on this protective element, it is urgent to inspect the hinge.

I remember how I changed ball joints for the first time in my life. It happened unexpectedly - I went to the village to a friend. Exciting fishing was expected. On the way to the lake, I had to brake sharply and turn the steering wheel. There was a crunch, then a knock, the car began to pull to the left. “The ball flew” - Tolya (my friend) said with the air of a connoisseur. Indeed, when the car was jacked up, it turned out that the "bullseye" jumped out of the nest - what a force the blow should have been! Apparently, the ball joint was also subjected to heavy loads before that - I often went to the primer, and I didn’t spare the “seven”, sometimes I drove through the field, stones and pits. Tolya went on foot for new hinges. The broken part was replaced on the spot, I later installed the second one in my garage. Fishing failed.

Hub

The hub is located in the center of the front suspension structure and is a round piece connected to the shaft. It has a bearing, the model and strength of which depends on the design tasks.

Thus, the hub consists of a body, metal wheel studs, bearings and sensors (not installed on all models).

The steering knuckle is an important part of the hub, because thanks to this component, the entire front suspension is integrated with it. The element is fixed with the help of hinges to the hub, steering tips and rack.

Front suspension problems

Suspension problems VAZ 2107 occur due to bad roads. First of all, ball bearings suffer, then the racks and other elements of the depreciation system fail.

Knock

Quite often, the owners of the "seven" complain about a knock when driving at a speed of 20-40 km / h. Then, as you accelerate, the dull sound disappears. Noise area - front suspension.

Experienced owners of the VAZ 2107 claim that knocking at low speed, which disappears as it accelerates, is associated with shock absorbers. They receive a vertical strike from below when the movement of the machine is weak. At high speed, the car levels out, knocks disappear.

Detailed instructions for the actions of the driver who noticed the knock are given below.

Video: what knocks in the front suspension

The car pulls to the side

If the machine begins to pull to the side, the steering knuckle or suspension arm may be deformed. On old VAZ 2107 cars, the loss of elasticity of the strut spring is not ruled out.

Basically, if the car pulls to the side, this is due to brake pads, steering play and other third-party reasons not related to the suspension. Therefore, it is recommended to act by elimination, and only then test the suspension.

Noise when turning

The hum when cornering is due to wear of the hub bearing. The nature of the noise is as follows: it is observed on the one hand, appears up to a speed of 40 km / h, then disappears.

Here's how to check the wheel bearing for play.

Suspension upgrade

The regular suspension of the "seven" is considered soft and imperfect. Therefore, many decide on tuning and improvements. This helps to significantly improve handling and overall comfort, as well as increase the life of springs, balls, bushings and other elements.

Reinforced springs

Springs are the main element responsible for smooth running, exchange rate stability and good handling. When they weaken or sag, the suspension is not able to compensate for the load, so breakdowns of its elements and other troubles occur.

The owners of the "seven", who often travel on bad roads or drive with a loaded trunk, definitely need to think about upgrading the standard springs. In addition, there are two main signs by which it can be judged that replacement of elements is needed.

Spacers are the first thing that comes to mind for the owners of the VAZ 2107. But such a conclusion is not entirely correct. Yes, they will restore the stiffness of the springs, but they will negatively affect the resource of the elements. Soon, cracks can be found on the springs reinforced in this way.

Therefore, the only right decision would be to replace conventional springs with reinforced or modified ones from the VAZ 2104. At the same time, it is necessary to change the shock absorbers to more powerful ones, otherwise the reinforced springs will easily damage the standard system.

Before starting the replacement procedure, you need to arm yourself with the following tools.

1. Lift.
2. A set of various keys, including balloon.
3. Crowbar.
4. Bruskom.
5. Wire hook.

Now more about the replacement.

1. Put the car on a jack, remove the wheels.
2. Remove struts or conventional shock absorbers.
3. Loosen the upper arm locks.
4. Place a block under the car, raise the lower arm with a jack.
5. Loosen the stabilizer bar.
6. Remove lift.
7. Loosen the nuts of the lower and upper ball joints, but do not completely unscrew them.
8. Knock out the support pin from the steering knuckle, using a pry bar and a hammer.
9. Fix the upper lever with a wire hook, and lower the lower one.
10. Pry the springs with a pry bar from below and remove them.

Then you need to release both springs from the gaskets, check the condition of the latter. If they are in good condition, install on a new spring using electrical tape. Put reinforced springs in place of regular ones.

air suspension

"Seven" has great potential in terms of modernizing the front suspension. And many car owners decide to install an air suspension with an electric compressor, hoses and a control unit.

This is real electronic assistant, which makes it possible to change the amount of ground clearance depending on driving conditions. Thanks to this innovation, the stability of the car at high speeds increases, long-distance trips become comfortable, the car goes through bumps more gently, in a word, it becomes like a foreign car.

System upgrade goes like this.

Electromagnetic suspension

Another upgrade option involves the use of electromagnetic suspension. It is a set of mechanisms and components that act as a link between the road and the body. Thanks to the use of this type of tuning suspension, a smooth ride, high stability, safety and comfort are ensured. The car will not “sag” even during a long parking, and thanks to the built-in springs, the suspension will remain operational even in the absence of commands from the on-board network.

To date, the most well-known manufacturers electromagnetic suspensions are Delphi, SKF, Bose.

The front suspension of the VAZ 2107 requires timely care and control over the main components. Remember that road safety depends on it.

VAZ 2107 in the original looks quite modest. The same modest are the dynamic characteristics of the car. Therefore, many car owners are finalizing and improving almost all components and systems of the car: appearance, the interior becomes more comfortable, engine power increases, etc.

Radical tuning VAZ 2107

You can turn a serial sedan that rolled off the assembly line at the beginning of the 21st century into a car that vaguely resembles the original using tuning. Examples of professional tuning can be seen at various international competitions, for participation in which cars are specially modified and finalized.

Concept of tuning

The term tuning literally translates from English as tuning or adjustment. Any car can be tuned to such an extent that it becomes unrecognizable. Each owner refines his VAZ 2107 in his own way, individually determining which components and parts need to be modified.

Before starting tuning both the car as a whole and any component, it is important to understand a number of simple requirements. Modernization of the car should not contradict Russian legislation and traffic rules (SDA). First of all, this concerns external tuning of the body, replacement of wheels and disks, external and internal lighting. Everything that is attached to the sides and front of the machine must not: have parts protruding beyond the dimensions, be poorly welded or screwed, contradict the requirements of UN Regulation No. 26.

There are three types of tuning.

1. Technical tuning: improvement of engine performance, refinement of gearbox, transmission, running gear. Sometimes this task is solved radically - standard units and mechanisms are changed to units and mechanisms from other car brands.
2. Interior tuning: making changes to the interior of the cabin. The design of the front panel, seats, ceiling is changing, which are sheathed with fashionable material, inserts are made of metal, expensive wood, etc.
3. External tuning: completion of the body. Airbrushing is applied to the body, body kits are installed, the configuration of thresholds, fender liner, etc. is changed.

An example of tuning VAZ 2107

The appearance of the VAZ 2107, shown in the figure, has changed a lot due to an unusual home-made front bumper, crate, front fenders and sills painted green.

Ground clearance decreased from the factory 17 cm to 8–10 cm, which gave the car a similarity to a racing sports car and had a positive effect on stability and handling. Painting made the car noticeable in the traffic flow. In this way, external tuning made the ride safer and gave the VAZ 2107 a memorable appearance.

Body tuning VAZ 2107

VAZ 2107 is ideal for external tuning for the following reasons.

1. The car initially has a discreet appearance.
2. On sale there is a wide selection of parts, accessories, accessories for tuning at affordable prices.
3. The car does not have complex electronics, automation, self-diagnosis systems that could be damaged during work.

Most often, external tuning is limited to window tinting and the installation of stylish rims. To give the VAZ 2107 body a streamlined shape is a practically unrealizable task. However, for speed characteristics car is not needed. It is possible to reduce the force of air flow under the bottom due to the installation of low-lowered spoilers, which harmoniously integrate with the base of the body at the places where the thresholds and bumpers are installed.

Attach to car body sporty look possible through:

Body kits and bumpers are made independently. It is very important to cut and bend them correctly. To do this, you can use special computer programs.

Windshield tinting

In accordance with the traffic rules tinted windshield it is recommended to do it only at the top with a strip width of no more than 14 cm. This will protect the driver's eyes from the sun's rays. To tint you will need:

• tint film 3 m long and 0.5 m wide;
• glass cleaner or shampoo;
• rubber scraper to remove water;
• napkins made of non-woven material;
• marker;
• sharp thin knife (can be clerical);
• roulette;
• spray bottle.

The tinting process itself is carried out as follows.

1. The windshield is removed from the body and freed from the sealing gum.
2. The glass is transferred to a bright, clean corner of the room, where there is no dust.
3. Glass on both sides is thoroughly washed with soapy water. Strong pollution is removed by means of solvent.
4. The tint film is applied to the outer side of the glass and outlined with a marker with a tolerance of 5–7 mm.
5. On the applied line, the film is cut with a sharp knife.
6. The protective layer is removed from the film.
7. The surfaces of the glass and the adhesive side of the film are wetted with soapy water.
8. The film is applied to a clean, damp surface. In this case, the formation of horizontal folds should not be allowed.
9. The film is gently pressed with a plastic or rubber scraper from the center of the strip to the edges. At the same time, wrinkles are smoothed out. It is advisable to warm the film with a building hair dryer. There should be no bubbles between the film and glass. If they appear, they should be driven out with a scraper to the side that has not yet been glued, or pierced with a thin needle.
10. The glass dries for several hours and is installed on the car.

headlight tuning

The easiest and most affordable way to tune the headlights and taillights of the VAZ 2107 is to replace standard light bulbs with LED ones.

To do this, they usually use a special tape with spotlights glued to it. In this way, you can make original running lights, angel eyes, etc. You can also purchase already tuned front and fog lights and taillights in car dealerships.

Tinted rear window and installation of a decorative grille

If the car owner does not have tinting experience, it is advisable to purchase the cheapest film for darkening. For rear window There are no light transmission restrictions. Tinting is carried out without dismantling the glass, as it is glued to the sealing gum. The work will require the same materials and tools as for the windshield. The film is glued from the inside in the following order.

1. The glass is washed with soapy water, and heavy dirt is removed with a solvent.
2. The tint film is applied to the outer wet side of the glass.
3. Toning is given the shape of glass. To do this, the film is pressed against the glass and smoothed out under a stream of warm air from a building hair dryer. In order not to overheat the tinting, the air temperature should not be too high. The hair dryer moves along the entire surface of the film, stopping at each place for 2-3 seconds.
4. The protective layer is removed from the tint film, and it is glued from the passenger compartment to a damp inside glass. Since the film has taken the form of glass, it should fit snugly enough. Water from under the tinting is expelled with a scraper.

Sometimes, instead of tinting, a decorative grille made of two-millimeter plastic is installed on the rear window, which can be purchased at a car dealership. For ease of installation, it consists of two halves and is easily attached to the rubber seal of the rear window from the outside. The grille can be painted to match the color of the car or left as is.

Roll cage installation

Protect the driver and passengers of the VAZ 2107 extreme situations installing a safety cage will help. The work on the installation of the frame is quite complicated. In order not to disturb the geometry of the body, careful sizing, welding and fitting pipes in the cabin using hand-held power tools will be required.

Tuning salon VAZ 2107

The original looks very modest. The lack of frills provides the car owner with ample opportunities for tuning. Before radical interior tuning, seats are removed from the cabin, doors are dismantled and disassembled, the steering wheel, dashboard and rear panels are removed, as well as trim from the floor and ceiling.

Noise insulation of the VAZ 2107 cabin

Internal tuning should begin with the installation of a new sound insulation, without which it makes no sense to install a high-quality audio system. During the installation process, preliminary preparation for tuning of all interior elements is carried out. Depending on the readiness of the body surfaces, the insulation can be installed either in parts or completely. First processed external wheel arches and the bottom of the car, then - the trunk, hood, floor and ceiling of the cabin, doors and instrument panel. After dismantling the engine, the partition in the engine compartment is isolated.

Necessary tools and materials

For soundproofing you will need:

• set of open-end wrenches;
• set of spanners;
• set of heads with extension and ratchet;
• building hair dryer;
• a set of screwdrivers with different blade shapes;
• vibration-insulating material on a mastic basis ("Vibroplast Gold" or "Silver") with a thickness of 4 or 8 mm;
• Shumka (products of the Shumoff and StandardPlast enterprises).

floor soundproofing

Floor soundproofing is carried out as follows:

1. The fasteners are unscrewed and the front and rear seats are removed.
2. The factory coating is removed from the floor.
3. The floor is degreased and treated with a special mastic.
4. The floor is covered with soundproofing material.

Experts advise laying thin Shumka in several layers without gaps and gaps. Noise isolation is more effective than when laying thick material in one layer.

Front panel tuning

There are a lot of opportunities for tuning the front panel of the VAZ 2107. You can fit it with expensive material, make inserts from aluminum, chrome or fine wood. For appliances, you can make LED lighting or install a GF 608 Gamma panel with on-board computer. The steering wheel can be replaced with an analogue from a foreign car, covered with leather or other material.

Obviously, before tuning, the dashboard must be dismantled.

Replacement upholstery and seats

You can effectively change the appearance of the cabin by replacing the seat trim, ceiling, front and rear panels, doors with more modern and practical materials. At the same time, it is not recommended to use fleecy materials (phlox, carpet, etc.). When cleaning such surfaces with a vacuum cleaner, their surface will quickly lose its original appearance. To replace the seat upholstery yourself, you will need a sewing machine and the ability to handle it.

On sale there are special inexpensive kits for tuning the VAZ 2107 interior, consisting of plastic decorative overlays on the dashboard, sun visors, armrests, door cards, acoustic grilles, etc. Such a kit can be matched to the color of the car and choose different versions.

Seat upholstery

The ideal option is to install more modern seats in the VAZ 2107 interior. Ideal for chairs Toyota Corolla manufactured in 1993-1998, the fastenings of which coincide with the standard seat bolts of the VAZ 2107. However, it is quite expensive.

For seat upholstery you will need:

• material (fabric or leather) for sheathing;
• foam rubber;
• glue "Moment" or equivalent;
• electrical tape or tape;
• sewing machine;
• thick needle;
• threads of a suitable color;
• sharp knife;
• awl;
• set of wrenches;
• hammer;
• Screwdriver Set.

Work is performed in the following order:

1. The front seat is removed from the rails and placed on a flat surface.
2. The old upholstery is torn at the seams. In this case, it is necessary to prevent damage to the edging.
3. Places where the skin is glued to cardboard inserts are wetted with gasoline.
4. The old upholstery is gently pulled off the backrest and seat cushion.
5. A pattern is made from the new material along the contour of the old skin with scissors.
6. On the sewing machine the trim parts and edging are sewn together with a double seam. Depending on the material, the joints can be stitched by hand, glued or heat-welded.
7. The foam rubber and sagging seat springs are being replaced.
8. Back and pillow front seat the new upholstery is carefully stretched.

The rear seat also folds in the same way.

Replacement door cards

Installing new door cards will also noticeably refresh the interior of the VAZ 2107. This is quite simple to do. As new cards, you can use plastic overlays under the tree. Alternatively, you can buy a set of various inserts for the VAZ 2107 interior in the store.

Interior ceiling trim

Some car owners attach hardboard to the ceiling of the VAZ 2107 cabin and already glue carpet on it. It is quite long and laborious, but the result is very effective. Before starting work, the windshield and rear windows are dismantled.

Sometimes the standard upholstery is changed to leather or some other material. However, before this, the sound insulation of the ceiling should be strengthened. For this:

• the factory noise is carefully removed;
• the metal surface of the ceiling is degreased;
• a vibration damper is glued to the degreased surface (experts recommend using a building hair dryer);
• a layer of splen is glued on the vibration damper;
• the surface is covered with factory noise.

Other possibilities of internal tuning VAZ 2107

Tuning salon VAZ 2107 can be supplemented:

• replacement or modification of sun visors and rear-view mirrors;
• changing the interior lighting with the installation of lamps for the legs;
• installation of a new radio and acoustic system;
• installation of electric windows;
• replacement of standard rugs with decorative ones;
• modernization of other parts, devices and devices.

Tuning engine VAZ 2107

The manufacturer installed on the VAZ 2107:

• carburetor engines with a volume of 1.2 and 1.3 liters;
• injection engines with a volume of 1.5 and 1.6 liters.

The most common types of tuning power units are:

• increase in the working volume of combustion chambers;
• camshaft replacement;
• installation of an air filter of zero resistance;
• conversion of the exhaust system to a straight-through muffler.

The installation of a turbo kit on the engine gives the greatest effect.

Ways to increase the power of the VAZ 2107 engine

You can increase the power of the VAZ 2107 engine in the following ways.

1. Tuning of a head of the block of cylinders. Due to this, you can increase the power by 15-20 liters. With. Since the head is made of cast iron, all operations for its completion are quite difficult and time consuming.
2. Carburetor tuning. The diameters of air and fuel jets are changed, enlarged diffusers are installed.
3. Installation of two or four carburetors.
4. Installation of a turbocharger, consisting of a compressor and a turbine.
5. Boring cylinders to increase their diameter.
6. Installation of forged lightweight pistons instead of cast ones.
7. Replacing the standard air filter with a filter of zero resistance.

On injection models VAZ 2107, it is recommended to carry out software chip tuning. This will not only optimize the performance of the engine, but also normalize the operation electronic block management. The effect will be maximum if chip tuning is performed on a serviceable engine that has passed a full technical inspection.

Tuning the exhaust system VAZ 2107

Some car owners make the engine sound louder to make it sound like the growl of a sports car. To do this, the catalyst is replaced with a special flame arrester. Other owners of the VAZ 2107 believe that tuning the exhaust system is justified if the result is an increase in engine power. When evaluating the feasibility of such measures, it should be borne in mind that improper installation will lead to an increase in fuel consumption and deterioration performance characteristics car. Therefore, work on tuning the exhaust system should be entrusted to professionals.

When tuning the exhaust system, do not forget that the maximum sound level of the engine should not be louder than 96 dB. Alteration of exhaust gas removal devices cannot worsen the environmental class of the engine.

Tuning the exhaust manifold and downpipe

For better exhaust gas purge, extreme people change the standard exhaust manifold to a StinGer spider complete with a double stainless steel intake pipe (pants). This allows you to increase power at high speeds by about 9 hp. With. At the same time, the formula for the output of exhaust gases "4-2-1" does not change.

Since the internal walls of the StinGer are smoother, the installation of such a collector will increase the efficiency of the exhaust gases and increase the power at maximum speed by 9 hp. With

The flat surfaces of the StinGer manifold flanges ensure a snug fit to the cylinder head and to the pants. However, the new downpipe does not have seat with thread for oxygen sensor. Therefore, if necessary, a nut is welded on this pipe in front of the catalyst, into which the sensor is installed.

Since the pants end with a flange, the resonator of the injection model is connected without problems. However, on carburettor VAZ 2107, this assembly is made differently, so it is better to immediately install a resonator from an injection engine on such a car.

Installing a straight-through muffler

The standard muffler VAZ 2107 consists of two pipes welded at different angles and lined with non-combustible mineral wool filler, which reduces the speed of exhaust gases and softens the exhaust. To increase the volume of the exhaust and make the flow of exhaust gases straight, an audio tuning of the exhaust system is carried out. Instead of a conventional muffler, a do-it-yourself straight-through is installed.

In a straight-through muffler, the exhaust gases do not make turns that dampen speed, and are additional resistance that reduces engine power.

Thus, with the help of tuning, you can turn the VAZ 2107 into a completely new car. In accordance with the wishes of the car owner, almost any components and parts are being finalized, including the engine. Elements for tuning are commercially available, and most of the work, carefully following the instructions of professionals, is quite simple.

This is a classic of the Soviet automotive industry. The car is really good in many ways. But, unfortunately, he also has a lot of shortcomings, especially for domestic roads. And the main one is the soft suspension. On the one hand, this is good, because it dampens bumps, and it is comfortable to drive a car. In addition, you get less stress on the spine. On the other hand, soft suspension impairs vehicle handling during maneuvers. Yes, and it is not particularly reliable.

As for the Classic specifically, it has always been and continues to be used as a workhorse. And an additional minus of the soft suspension on this car is that with heavy loads on one of the axles, the car starts to “sag”. It comes to the fact that the wheels begin to cling to the arches. As for the options for improving the suspension, there are many. If finances allow, you can contact tuning specialists and they will make significant improvements. If the budget is limited, you will have to do everything yourself.

Highlights of suspension tuning VAZ 2107

The first thing that can be done when upgrading the front suspension is to install a spring from NIVA 2121. The fact is that such a maneuver does not require additional preparation, since the spring fits well into the scheme. In addition, it will allow you to get more rigidity. It is worth noting that the same operation can be carried out with the rear suspension. Some motorists cut off one or two turns to reduce clearance. Do it or not - it's up to you. Lower clearance has its advantages, and we will talk about them in this article. But there are also significant drawbacks.

The next step is to replace the stock shock absorbers. Everything here depends solely on your capabilities. If you want to save money, you can put a fairly inexpensive Ikon. Installing sports like Bilstein will cost more. But the effect will be much greater. The main rule when replacing shock absorbers on the Seven is that they must be gas-oil. Their advantage lies in greater elasticity. What is the output? Such modernization will lead to the appearance of large rolls when cornering. To minimize them, new stabilizers with a higher degree of rigidity are usually installed (as an option, you can pair a pair of factory ones on both sides).

What else can be replaced in the VAZ 2107 suspension

Tuning the VAZ 2107 suspension should not be limited to work under the car. It is advisable to take care of improving the steering system. As an option - a steering column from Niva. It is possible to install an electric booster. But such work is best left to professionals. The fact is that the equipment must be correctly connected. Doing it yourself is quite difficult.
In addition, experts recommend paying attention to the braking system.

Installing disk will significantly improve the performance of the car. Finally, you can complete all the work by changing tires and carrying out wheel alignment. Tires are better to choose foreign. Both the classic version and the low profile are possible. But it is worth remembering that the latter is good in terms of handling, although it reduces the level of driving comfort.

Suspension lowering as an option for tuning it

Many motorists prefer that the greater the ground clearance (the so-called ground clearance), the better. And they are partly right. Domestic roads can very quickly "kill" a low suspension. However, when tuning, some owners of the Seven set themselves completely opposite goals. They want to lower the suspension, giving the car a sportier look. How logical is this in conditions of poor road surface?

In fact, low suspension has its advantages. For example, the handling of the car in corners is improved. This is achieved due to less roll (the level of the center of gravity decreases). Another advantage is to change the appearance of the car. She becomes more athletic and aggressive. Finally, the reduction of resistance allows to achieve a reduction in fuel consumption.

About the dangers of low ground clearance

Before you decide to make such drastic changes to your "Seven", it is impossible not to mention the dangers that may lie in wait for you on the road. Important information! Before you decide to lower the clearance of your car, consider whether it is worth it. There are several points that we recommend paying attention to:

• the possibility of damage to important parts of the car when hitting pits. At least you will visit the service station much more often;
• if the work is carried out by unskilled specialists, the car will very soon require additional cash injections.

The main options for reducing ground clearance

The first option, which is considered the most economical, is to shorten the standard springs. You can do this with your own hands or, if you don’t have the necessary tools and skills, entrust it to a novice specialist. A similar operation can be performed without dismantling the spring. It is important to remember that the springs are shortened by a different number of turns (the front, for example, by two, and the rear by three). This is due to the fact that the weight of the machine must be distributed evenly.

The advantage of this method is the low cost. As for the disadvantages, these include the risks of breakage of both the spring and the shock absorber. Another option is to buy and install shortened springs. Such springs are often called sports. The main costs here are associated with the purchase of finished parts. The advantages of this method include the fact that you can return everything to its place at any time (after all, regular springs are not shortened). In addition, you can carry out such an operation yourself. The only thing, upon completion, you need to contact specialists to carry out work on the collapse / convergence.

You can also lower the clearance with the help of a coilover. These are springs that allow you to adjust the clearance. This option is the most convenient, because even if you could not achieve the expected result the first time, you can always adjust the desired suspension height without resorting to buying new parts. The advantages of this method include the versatility of coilovers. They are installed with both sports and conventional shock absorbers. They are adjustable to your liking. Finally, they are easy enough to install with your own hands. As for the minuses, there is only one - the price of the issue.

Air suspension is another "pump" option. Moreover, this option is only suitable for true fans. The fact is that the cost of a package can reach tens of thousands of rubles. But for the money you get your hands on a complete tool for working with the suspension. Another disadvantage is the cost of work. The fact is that such a suspension cannot be made in your garage. And it is also not recommended to entrust the installation of equipment to the first “specialist” who comes across. The disadvantages include the fact that such a suspension can quickly fail on domestic roads.

The advantages of this option include the possibility of flexible regulation of clearance (in the range of up to five centimeters). If the system is installed correctly, you will be able to adjust the ground clearance at your discretion at any time, depending, for example, on the type of road surface and terrain. Another important advantage is the ability to hold the maximum weight of the car well. The machine does not sag even at its maximum load. In general, you can adjust the clearance in the range from two to nine centimeters. It is not worth doing more, as this is fraught with certain risks. In the process of refinement, it is also recommended to mount new anthers and rebound buffers. In addition, experts advise changing the thrust bearings. And one more important point. All suspension work must be approached responsibly. If you cannot perform some operation yourself, it is better to entrust it to professionals. Saving or doing something carelessly is inappropriate here. Any mistake can significantly affect handling.

Video tuning suspension VAZ 2107

The desire for tuning begins with discomfort, when everything is as it should be, but something is still wrong. And the rest of the actions already depend on the driver himself - someone has enough instrument clusters with the original design of the scales, and someone wants to upgrade almost every element of the vehicle.

Due to the high demand for tuning certain elements, the shops simply overflowed with a variety of accessories, auto workshops had to recruit specialists in tuning of varying complexity, and thematic publications appeared on the shelves of kiosks.

Our article will not be replete with giant pictures, since the emphasis is on information, not images.

Every motorist wants his vehicle to be perfect in all aspects, from interior elements to the engine.

For the most part, the improvement of the vehicle stops at the installation of aerodynamic elements, sports locks, mufflers, steering wheel and seats. There is nothing shameful in striving to see your vehicle not as the manufacturer intended it to be. It all depends on the tastes of each person. However, it is important to know when to stop, since an excessive passion for tuning makes the car look somewhat strange and incomprehensible.

There are other tuning enthusiasts who dream of improving the engine. They just simply torment car engines, expanding the working volumes, the compression level, modernizing the crankshaft and timing, performing chip tuning, installing nitro and other elements. But here it’s already worth thinking about, because such methods that increase the power of the vehicle require an increase in responsibility for the owner in the form of additional obligations.

The reason is that any, even a weak vehicle, is dangerous in itself, and if the car just has huge power that is not comparable to the braking dynamics, then it’s already worth considering. How can you protect yourself, and how to protect others from possible dangers? It is wrong to believe that a motorist who decides to increase the power of the motor will limit himself in the speed of movement, because such operations are performed to squeeze all the forces out of the motor. The speed will increase, and any serial unit is simply unable to cope with the assigned tasks. The suspension and its average characteristics are completely unsuitable for this business, the brakes even reach a critical operating mode. Standard tires unable to provide the car with the filigree that is needed for intensive driving at high speed.

However, in general, the modernization of the suspension brings with it such advantages: a decrease in body turns during cornering, longitudinal and transverse rocking and a number of other nuances almost completely disappear. In addition, the suspension as a whole becomes very stable.

tuning problems

When on slippery road the flow of cars is overtaken by a dull-toned car with a raised stern, ten minutes later you have to watch the work of rescuers who get a vehicle that has fallen into reinforced concrete fenders. After this, involuntarily, I want to ask a rather obvious question. The old adage that you should not pick up a lot of speed without proper confidence will be relevant at all times. In such cases, it remains to advise a banal rule - never exceed the speed limit, contrary to your desires.

A professionally sharpened tool requires a confident and firm hand. Therefore, the approach to the expedient exploitation of all the power reserves of an extreme vehicle should be as serious as the attitude of doctors to their work in the course of operations. A quality scalpel will become useless and dangerous in the hands of an amateur who has never opened an anatomy book. Because professional driving skill is much more important than a boosted engine, reference suspension and modified brakes.

For each driver, such traits as a calm character and patience with other drivers or pedestrians are important. You don’t need to turn on the signal for pedestrians with or without reason, you don’t need to scare them by picking up speed after the green light is on. You also need to be more sensitive to drivers for whom driving a car can lead to stress. Old women, children, young mothers also need to be treated more condescendingly. Of course, after a hectic day, it's easy to forget about it, and you want them all to move faster. But still, you need to understand that city streets are not the best place for rapid acceleration.

Before you get behind the wheel of a vehicle, it is worth considering such nuances: will the gasket between the steering wheel and the seat withstand the power that the head gasket can handle? If you cannot answer yes to this question, then it is better not to use the full potential of the machine in one fell swoop. Well, if ambitions are overflowing, it makes sense to visit a school focused on extreme driving. Given the situation on domestic roads, it will be very, very useful. At the end of their studies, few drivers will step on the gas without thinking everything through in advance. After all, a person tends to acquire not only specific skills, his attitude to driving a car as a whole changes as a phenomenon.

Before proceeding with the finalization of the vehicle, it is important to know specifically what it will be, how radical the changes will be, and what they will bring with them. It's one thing to put on pedal pads, a chrome-plated gear knob, sports seats and a steering wheel. But intervention in the design of the motor, suspension, brakes and body is a completely different matter. Although both branches fall under the same category.

It is also important which vehicle will be modified. It is possible to make sports vehicles out of rare cars, but there is practically no point in this. Putting a powerful engine on a rarity is only half the battle, in order to realize its potential without harming yourself and others, you will need to revise the design of the vehicle as such. True fans of this activity, of course, no one can stop, but for an ordinary motorist, this idea will seem difficult to implement and hard on the pocket. Therefore, the choice must be final and complex. A process such as suspension tuning requires compliance with a certain regular sequence. First of all, you need to do everything in a logical way, due to which the transport will acquire a new character, the degree of rigidity of which rests on the wishes of the owner.

It is also worth paying attention to the brake system. It makes sense to work on the reserve.

In the future, proceed to the design of the motor. At this point, an extensive choice is provided for activities: from multifaceted improvements to the standard motor and ending with the installation of a more powerful option. It also depends on the tastes and priorities of the owner.

Having received an engine with other characteristics, it becomes necessary to get an engine aggregated with a transmission in order to get the most out of it. As you know, a standard box in combination with a GPU with an updated engine will interfere with the smooth operation of the system, so a selection of rows and gear ratios will be required.

Alternatively, you can calculate in advance, starting from the power of the motor, calculate the necessary transmission and braking parameters. Having decided on the operating conditions of the vehicle, you need to start selecting the optimal suspension characteristics, including wheels and tires.

Having dealt with undercarriage, you can take on the exterior and interior decorations. There is also an extensive selection: unique lighting devices, aerodynamic solutions, image application and other interesting things. Changes to the interior can also hardly be called something incredibly complex - additional devices, sports seats and a steering wheel, various linings and controls, floor mats, as well as many other elements that give the car individuality.

The first stage of suspension modernization

People who have always dreamed of unlimited freedom have always been attracted by the idea of ​​long-distance travel. However, there are many places where you can’t go on foot, so the man had to tame the horses. Traveling alone proved dangerous and boring, and the poor artiodactyl was unable to carry more than one or two people on his back. And this is not to mention the road belongings in - that's why the idea of ​​\u200b\u200bthe wagon came to people. In between admiring the beauties of the surrounding landscapes, people were increasingly thinking about the comfort of travel, which was the reason for the appearance of a leather belt. The belt was replaced with wooden springs. But then they were also supplanted by more practical metal variations.

Many years later, the horses were replaced steam engines and first engines.

The speed increased more and more, just as the demands on the vehicles themselves and the drivers increased. Safety, handling, ride, comfort and durability were the main factors. A complete overhaul was needed not only design features suspension, but also the vehicle itself.

Suspension elements can be divided into: basic and additional. The main features are divided into steel products, gas and pneumatic elements, rubber, and plastic products. Their task is to hold the body in a specific position and ensure the elastic interaction of the vehicle with the road.

Additional elements include hinges connecting elements of a movable type in a suspension with a body. They are necessary to suppress oscillations and vibrations in the high frequency range.

If we talk about specific elements - springs, then they are divided into linear and progressive. In the first case, the spring stiffness changes in proportion to changes in length. These coil springs with fixed pitch and bar thickness are designed for safe and extreme comfortable ride on a flat road.

In the second case, the spring stiffness changes regardless of changes in length. There are cylindrical shapes with variable pitch. They got their name due to a significant increase in stiffness during the compression process, avoiding holes and increasing the controllability of the vehicle.

It is also important to note the composite elastic elements, consisting of a pair of springs of different stiffness. They are separated by a special washer with the required level of elasticity or rigidity.

This option will reduce the vibration from a small fluctuation, due to the work of the elastic element of a small rod diameter and with a small step. Thanks to the second, stiffer spring, suspension holes are excluded in case of large damages on the road. As a result, the vehicle will receive good handling without sacrificing comfort.

shock absorbers

These elements are necessary in order to dampen body vibrations caused by road irregularities or inertial forces. Prevent vibrations of wheels, tires, wheel brakes, axles, axles, beams, hubs, and levers in relation to the body.

It is the efficiency of its workflow that affects comfort and safety, since in addition to reducing vibrations, its tasks include ensuring the reliability of contact between the wheels and the roadway.

The most common in modern suspensions are hydraulic and hydropneumatic shock absorbers, characterized by reliability, efficiency and manufacturability.

Their workflow involves converting a specific amount of kinetic vibrational energy into heat and dissipating heat. The amount of this energy depends on the mass of the vehicle, the spring stiffness and the frequency of vibrations. According to the principle of operation, they are based on the viscosity and compressibility of the liquid.

Shock absorbers can be divided into three types:

• Two-pipe hydraulic type solutions.
• Two-pipe hydropneumatic type solutions.
• One-pipe hydropneumatic type solutions.

If we talk about twin-tube pneumatic shock absorbers, then they have long become classic representatives of the family of hydraulic variations.

Two-pipe variations are characterized by the correspondence of the axes of the cylinders. The outer cylinder is called the reservoir, while the inner one has no other name. The cylinder contains a movable piston on which a bypass type valve is mounted. The lower part of the cylinder houses the bypass and compression valve, each of which was mounted in a separate housing. The cylinder is filled to its full volume with shock-absorbing liquid, the reservoir is only two-thirds, and the free space above the liquid is filled with air.

The damping process is carried out due to the hydraulic resistance provided by water when circulating through the valve system. The resistance, as well as the level of stiffness, are regulated by the aforementioned valves. The bypass valve allows fluid to flow in a specific direction.

In the process of shock absorber compression, water flows from the area under the piston to the area above the piston, and the volumes of liquid displaced by the parts of the incoming cylinder rod enter the reservoir from the outside. During release, the process is reversed.

It is worth dwelling in detail on a single-tube hydropneumatic shock absorber, commonly referred to as a "gas" shock absorber.

According to the principle of operation, it is similar to the two-pipe version: damping is performed due to the passage of fluid through calibrated compression and rebound valves. In this case, each valve is located on the piston, and the only pipe plays the role of both the body and the cylinder, therefore there is no reservoir as such. Now let's talk about physics. A liquid cannot be compressed, but in the case of a gas, everything is different - it can be compressed. This property was used by designers in the process of developing elements. They placed a separating piston at the bottom of the cylinder, and also pumped neutral nitrogen into the resulting volumes. As a result, the volumes of liquids displaced by the piston during the compression process are compensated by the compressible gas, which is located below the separating piston.

Recently, they have been trying to introduce, and in some cases have already commercially introduced shock absorbers controlled by electronic technology. In addition, systems are operated with a half active type control, due to which the shock absorber is adjusted, starting from speed limit vehicle.

Designs used

As you know, there is always something to strive for, even if the path to striving is not always obvious.

Therefore, each new technical solution surprises with its verified complexity or simplicity, however, both categories prioritize the modernization of the qualities of the vehicle. We will not be able to study each of the available pendants, therefore it is worth dwelling on the most famous ones.

It is important to note that suspensions are divided into two main types: dependent and independent. The former are used on trucks and heavy off-road vehicles, therefore they are not the cornerstone of the article. Well, the independent type is the most appropriate for this article, since it is used in cars.

The most common designs of independent rear axle suspension with longitudinal, transverse or oblique levers.

Front and rear axles can be used in the case of MacPherson strut, upper and lower A-arms and oblique arms.

All of them are characterized by a variety of kinematic possibilities, as well as pros and cons, which make little sense to focus on. But in the case of general system requirements, it is better to remember.

Everyone knows that the characteristics of the suspension are directly related to the various parameters of specific parts and their interaction. Manufacturers of serial vehicles always make a choice in favor of average options. No one will allow you to reduce the level of security for the sake of comfort, and the reputation of such actions will be damaged. At the same time, cutting comfort for the sake of safety is also a highly irrational decision.

Therefore, manufacturers are trying to find a certain compromise that can satisfy the average consumer.

If we talk about the topic of requirements for ordinary transport, then we will not touch on them and will turn directly to the topic under consideration.

To obtain the required return, it will be necessary to replace the characteristics of the elements of the elastic and damping type. It is worth starting with elastic elements.

The softness of the springs and the large suspension travel serve as the forerunner to a high ride smoothness, sufficient freedom of body longitudinal oscillations and acceptable contact of the wheels with the road surface. However, there is one important drawback regarding the softness of the spring.

This factor is the cause of large overweight of the body when turning and a decrease in the ability of the tires to respond to side-type forces. In other words, when cornering, the vehicle will deviate from the planned trajectory, making the speed pass very problematic. It follows that fast driving requires a suspension with high stiffness and short travel.

How can this be done? The answer is quite simple - by installing modified springs and shock absorbers. In addition, you can look at progressive springs, which is useful if you want to lower the vehicle's ground clearance.

In terms of damping solutions, dampers with rigidity contribute to excellent wheel-to-road contact, with little loss in smoothness.

You can talk about the advantages of shock absorbers and springs for a long time, but it is worth reducing the unsprung masses. That is the purpose of light alloy and forged wheels. Tires are also worth noting, because high-type profile rubber can negate almost any transformation in the suspension, regardless of its stiffness.

First of all, this is a decrease in body roll during cornering, longitudinal and transverse rocking and a number of other nuances almost completely disappear. In addition, the suspension as a whole becomes very stable.

In addition, the vehicle will become more responsive to one or another turn of the steering wheel, having lost the pause characteristic of stock variations when changing lanes, and sharper reactions will dominate in habits. It is also worth noting that the clearance will be reduced, thereby reminiscent of sports cars

Possible problems

It is worth remembering that elevated level stiffness of the suspension elements will not affect the body in the most desirable way: dynamic loads to which power elements are susceptible will be increased, the body will be more loaded with vibration. Since when hitting an uneven surface, the same amount of energy is extinguished as in the case of a soft serial spring and shock absorbers in suspensions with a long but shorter stroke, and this feature helps to reduce the life of the body, contributing to premature destruction of ball bearings, hinges, motor mounts.

With a significantly reduced clearance, it is not recommended to meddle on broken country roads for obvious reasons. And in urban areas, you can accidentally catch on something with the lower part of the bumper or suspension arm. At best, these will be small stones.

However, the clearance issue is not as scary as it might seem. Many companies involved in the sale of elements for the element in question make kits that include shock absorbers and springs with pre-selected characteristics. In addition, developments are presented that are capable of adjusting the clearance and the level of rigidity in a fast topic and in a wide range. It follows that it is possible to obtain add-ons for virtually a variety of conditions of use, thereby satisfying any request with just one set.

Each owner domestic car VAZ 2107 must know how the suspension of the car is arranged. Chassis needs to periodic maintenance involving the replacement of worn-out elements. You can do these works with your own hands, if you know how to properly remove or install this or that part. In this article, we will tell you about it in detail.

VAZ 2107 - the last car of the domestic automaker, produced according to the classic layout, that is, with rear wheel drive. Many Russian motorists prefer rear-wheel drive cars, so the so-called seven is still popular today. running car consists of front and rear suspension. The front one has a fairly simple design, so everyone can handle its periodic repairs.

How is the front suspension set up?

View of the levers from below

The front suspension of the VAZ 2107 has an independent design and consists of two levers: one on top, the other on the bottom. There is also a coil spring and a telescopic shock absorber-rack. The suspension has an anti-roll bar.

The lower arm with an axle is firmly fixed to the suspension cross member with bolts, and it, in turn, rests on the front spars. The upper arm is attached to the mudguard strut, but the arm does not have its own axle - it is a long bolt that goes through the strut.

To ensure the rotation of the levers around the axis, silent blocks are provided in the design, which are rubber-metal hinges. At the ends of the levers there are ball joints, to which a steering knuckle with a trunnion is attached to install the hub. The coil spring is located between the mudguard post and the lower arm. To prevent it from moving, the ends are installed in the support cups. Inside the spring is a hydraulic shock absorber. The shock absorber housing is attached to the lower arm through a rubber-metal hinge.

The shock absorber rod is attached to the body through rubber cushions. The anti-roll bar is attached with its ends to the lower arms of the undercarriage, and in the center to the spars. To prevent contact of the spars with the stabilizer, rubber cushions are located between them.

Possible breakdowns of the running gear

VAZ 2107 suspension malfunctions include wear on the rubber suspension elements, and ball bearings may also wear out. Sometimes springs and shock absorbers fail during operation.

You can repair the front suspension of the VAZ 2107 with your own hands in garage conditions, but first you need to diagnose its condition. Drive the car into an inspection hole or overpass, and during the inspection, determine the condition of the rubber elements, check all the gaps in the ball joints and make sure there are no oil leaks from the shock absorber, and also check the integrity of the spring.

To check the condition of the shock absorber with your own hands, you need to properly press the fender of the car from above, achieving compression of the shock absorber. Then let go and notice how the car behaves. The shock absorber should instantly take the initial position without unnecessary fluctuations. If the struts are worn out, the machine will wobble and need to be replaced.

Ball joint replacement

To replace the ball bearings, it is necessary to dismantle the wheel and clean the suspension elements from contamination. After that, place a jack under the lower arm and lift it - this is how you load the suspension of the VAZ 2107.

Using a wrench, unscrew the nut of the upper ball joint pin, and then press the pin out of the steering knuckle. As soon as the finger is out of the fist, unscrew the ball mount and remove it from the upper arm with a protective cover. Instead of the old ball, insert a new one and assemble everything in the reverse order. The lower ball joint is changed in the same way. After replacing them, contact a service center to adjust the camber and convergence, since you will not be able to do this yourself.

Replacement of silent blocks of levers

To replace the VAZ 2107 silent blocks with your own hands, you will need not only keys, but also a special puller. If they are in the upper arm, it will have to be completely dismantled, and in the case of the lower arm, this is not necessary. To remove the upper arm, press the ball joint pin out of the steering knuckle. Next, remove the bumper mounting bolt and unscrew the nuts holding the upper arm axle, and then remove it. Remove the upper arm from the machine.

After that, using a puller, you need to pull out the worn silent blocks, and then use it to insert new ones. The lever is mounted in the reverse order, but to install the ball joint pin, it is necessary to load the suspension with a jack placed under the lower lever.

To replace the silent blocks of the lower arm, it is not necessary to remove it. Just unscrew the nuts of the lever axle and remove the hinges with a puller. Then install the new ones in their places and tighten the nuts. You need to remove the lower arm if it is damaged, but this is rare.

Replacing shock absorbers

When the shock absorbers are worn out, they have to be replaced. If one of them is broken, you still need to change them in pairs. To replace the shock absorber, first unscrew the stem mounting nut, and then remove the washers and the upper rubber cushion from the stem.

Unscrew the lower rack mounting bracket from the lower arm, and pull out the failed shock absorber through the technological hole in the arm. Next, remove it from the mounting bracket and install the new rack in reverse order.
