How to do tuning and strengthening the suspension of VAZ cars. How to properly tune and strengthen the suspension of VAZ cars Overhaul of the front suspension of the VAZ 2107

"Seven" - the last rear-wheel drive car in model range VAZ. The front suspension of the VAZ 2107 has fewer parts than the “older” front-wheel drive models, so repairing it is easier.

Front suspension device VAZ 2107

The "Seven" is equipped with an independent suspension, consisting of an upper and lower arm, a spring and a shock absorber on each side. The lower arms are connected to each other through the stabilizer roll stability.

The axes of the lower arms are rigidly attached to the cross member (beam), which is fixed to the front spars of the body. The role of the axes of the upper levers is performed by the mounting bolts, with which the levers are bolted to the racks of the mudguards.

The mobility of the levers is provided by rubber-metal hinges - silent blocks.

The wheel hub is bolted to the steering knuckle, which is held at the ends of the levers by ball bearings (upper and lower). This ensures that the wheels turn around a vertical axis.

The front suspension springs, which smooth out bumps when driving over rough sections of the road, are located between the lower control arms and the mudguard. That the springs did not move during the ride, their edges are inserted into the support cups.

Shock absorbers that absorb vibration energy are attached to the body of the lower arm, and their rods are screwed to the mudguards through rubber pads.

The anti-roll bar is connected to the arms and spars through rubber bushings to eliminate direct metal contact and compensate for shock loads.

Malfunctions of the front suspension VAZ 2107

Repair or replacement of the VAZ 2107 front suspension is required in case of wear or breakage of its parts. Rubber and rubber-metal bushings, shock absorbers and ball bearings are most subject to wear. The breakdown of the latter is the most dangerous, since the steering knuckle in such cases turns out along with the wheel, and the car loses control.

To determine the breakdowns, it is necessary to inspect and diagnose the condition of the front suspension.

The inspection consists in checking the absence of oil leaks from the shock absorbers, the condition of the rubber parts of the parts and the integrity of the spring.

Checking the details of the front suspension VAZ 2107

It is easy to check the condition of the shock absorbers: press hard on the wing, forcing the spring and shock absorber to compress and release. The machine should return to its original state and not continue to sway.

The condition of the ball bearings can be assessed by checking the play of parts with a loaded and unloaded suspension.

All rubber parts (anthers, bushings, silent blocks) must be changed at the first sign of wear or damage. Silent blocks must also be replaced if there is play on the lever on the axle.

Replacement of ball bearings VAZ 2107

To replace the ball joint, you need to jack up and remove the wheel. Then unscrew the nut holding knuckle support pin and press out the last one.

After that, you can unscrew the support from the lever and remove it together with the anther. It remains to install a new ball joint with a new boot and assemble by performing the previous operations in reverse order.

After replacing the ball joint, it is desirable to adjust the angles of the front wheels (alignment).

Replacement of silent blocks VAZ 2107

Repair of the front suspension of the VAZ 2107 often requires the replacement of silent blocks. To carry out this operation, it is necessary to remove the upper arm. Lower control arm bushings can be changed without dismantling the control arm from the vehicle.

Silent blocks are pressed out of the lever and pressed into it using a special puller. To remove the upper arm, it is necessary to press out the support pin.

The silent blocks of the lower arms can be replaced by unscrewing the nuts on the arm axle. It is worth removing the lower levers only for replacement with new ones. But such an operation is usually required only when eliminating the consequences of an accident.

Replacing the front shock absorbers VAZ 2107

The front shock absorbers of the VAZ 2107 cannot be repaired, therefore, in case of poor performance or the presence of oil leaks, they are replaced with new ones. To replace them, just unscrew the two fastening nuts on the lower arm and the nut that secures the shock absorber rod in the mudguard cup. The shock absorbers are removed and inserted through a hole in the lower arm. To get or insert the shock absorber, it must be compressed.

Replacing the front springs VAZ 2107

The front suspension springs are replaced after the shock absorbers are removed and the anti-roll bar is undocked (the latter prevents the levers from moving freely). Also, to replace the spring, loosen the nuts securing the lower arm axle.

To lower the lower arm as much as possible and release the spring, it is necessary to press the lower ball joint pin out of the steering knuckle.

A new spring must be compressed and fixed with special ties before installation.

The assembly of the node is carried out in the reverse order. Couplings from the spring can be removed only after attaching the ball pin in the steering knuckle.

Repair of the VAZ 2107 suspension is not particularly difficult and does not require special knowledge and special qualifications. The only question is the presence in the garage of a special tool (pullers and couplers) and an inspection hole.

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 combinations with original design scales, and someone will want 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 it was perfect in every aspect, 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 install pedal pads, a chrome-plated shift knob, sports seats and 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 independent suspension rear axle 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 suspension performance is directly related to various parameters specific details 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.

Do not think that only tuning enthusiasts are engaged in the installation of additional car structural elements.

Many car owners often do this in order to give domestic car, for example, a VAZ car, better driving characteristics.

Today we will talk about the main types of modifications to the suspension of VAZ 2107, 2109, 2110, 2106, 2112, 2101.2105 cars made by drivers, and also evaluate the feasibility of installing them.

Here are the basic principles of the correct approach to tuning the suspension of VAZ cars and others. domestic cars and how to enhance it.

And although the installation procedure for individual additional suspension parts for many VAZ cars is the same, you still need to understand that installing them on the VAZ 2101 and 2112 will be different.

The most popular element, widely used by many owners Russian cars, is the front cross brace.

Its installation is carried out in the area of ​​​​the upper shock absorber supports, by fixing it between the glasses of the racks.

The main purpose of this part is to increase the angular rigidity of the body and improve the quality of vehicle handling.

In addition, the presence of a strut helps to eliminate the “float” of the geometry of the suspension arms, which occurs as a result of strong impacts on road pits or bumps.

The main reason why many motorists, in particular owners of VAZ cars, make such improvements is the lack of body rigidity, which contributes to poor handling, a feeling of “sluggish” steering and excessive rolls that occur during maneuvers.

It only shows up when driving. high speeds, mainly associated with trips on country roads.

Those drivers who spend most of their time within the city and are accustomed to a calm, leisurely ride may not notice these shortcomings.

The spacer is a fairly thick metal bar, either of a fixed length, intended for specific car models, or endowed with the possibility of spatial adjustment, which facilitates the installation of the element on different cars.

Its installation is carried out when the machine is placed on a flat surface by screwing several nuts onto the upper studs of the shock absorber mounts.

If for some reason the mounting holes do not match, the car body must be slightly “pulled up” in the right direction.

Installing a cross bar makes a certain sense. You will not only significantly increase the car's handling, but also extend the "life" of its body, thanks to improved torsional resistance.

Auxiliary support of the power unit

The purpose of supplementing regular engine mounts with another auxiliary module is to minimize the amplitude oscillations of the engine during sudden braking, acceleration and overcoming road hills or pits.

Its presence eliminates the so-called "pecking" - inertial phenomena that occur during the operation of the car.

The presence of an auxiliary support also prevents spontaneous disengagement of the transmission gears.

This greatly reduces the risk of unpleasant incidents that directly affect safety.

As a rule, it is difficult to install this component yourself.

It requires a certain skill that an ordinary motorist does not always have.

Separately, we say that some engine models involve the installation of a fourth support only after the transfer of the ignition unit.

This, on the one hand, is an additional difficulty, but, on the other hand, it significantly improves the operating conditions of the electronic module, moving it away from the road, thereby reducing the amount of dirt falling on it.

Additional support power unit often installed during tuning the suspension of VAZ 2109, 2110 cars.

Rear beam stabilization bar

The element considers as its purpose the reduction of the lateral rolls of the car, the improvement of the interaction of the wheels with the roadway when cornering, as well as the distribution of the load between rear shock absorbers when driving over bumps with one of the wheels.

The fact is that when it gets into deep potholes, an extremely strong hanging occurs, often causing the rear shock absorber rod to tear out.

When working in compression, the shock absorber, on the contrary, is unnecessarily prone to breakdown, which seriously affects its durability.

This does not happen when boosted. The resulting force effect is distributed between both wheels with an approximate ratio of 3 to 2, which has a positive effect on the quality of control and the reliability of the suspension elements.

Installation of the stabilization bar is made directly on the rear beam of front-wheel drive models domestic cars VAZ and others.

Mounting the beam reinforcement should not cause any problems for most drivers. To do this, you need to use a flyover or a viewing hole, and then, according to the instructions, fix the bar on the beam.

The only difficulty that may arise is the need to drill eight holes in the beam housing.

The front stabilizer bar of increased rigidity is a tool designed to significantly improve the quality of vehicle handling.

Its main difference from the standard part is the harder rubber bushings placed at the fixing points.

The VAZ 2107 car is a classic of the Soviet and Russian automobile industry. Millions of such cars roam the expanses of our country and neighboring countries. The owners are trying to improve their performance, for which they do tuning of various parts. But high-quality tuning without upgrading the suspension is impossible, and the suspension on the VAZ 2107 model is neither reliable nor practical.

1 Suspension tuning on a VAZ 2107 car

The factory suspension of the VAZ 2107 is too soft and imperfect. As a rule, with a certain loading of the trunk and the transportation of several passengers, the car noticeably sags, overload is felt, and in some cases the wheels begin to touch the arches. That is why, after increasing the rigidity and replacing some of the suspension units, the car's handling and overall comfort level are significantly improved.

The amount of suspension depends on the financial capabilities and desires of a particular car owner. With a solid budget and contacting a tuning shop, you can seriously "pump" the front and rear suspension and get sport car with improved features. However, many are trying to upgrade the suspension on the VAZ 2107 with their own hands, spending the minimum amount of finance and getting the maximum effect from the work done.

2 Features of the modernization of the front and rear suspension

To increase the rigidity of the front suspension, many resort to installing springs from the domestic SUV Niva 2121. They fit perfectly into the technical suspension scheme of the "seven" and provide greater rigidity. Niva springs are also suitable for the rear suspension, while they can be installed with or without cutting (some cut one or two turns to lower the clearance) and it is imperative to replace the rubber bumpers.

Next, you need to replace the factory shock absorbers. Which ones to choose also depends on financial capabilities. You can put cheaper options, such as Icon, and you can install sports shock absorbers Bilstein, however, in the second case, the price will be significantly higher. It is best to install gas-oil type shock absorbers when modifying the suspension. They have a fixed stem and will give greater elasticity to the front of the car.

With new springs and dampers, the car will roll more when cornering. To reduce roll to a minimum level, new anti-roll bars with an increased degree of rigidity should be installed. In this case, you can install additional stabilizers or pair two factory ones on each side.

3 Additional changes to improve handling

After changes in the front and rear suspension it makes sense to think about improving the steering. The easiest option is to install a steering column from the same Niva. In this case, you can install an electric power steering, which will need to be properly “fitted” to the new column. It is better to entrust these changes to professionals, while they are not mandatory, this can only serve as an additional "option" for improvement driving performance car with reinforced suspension.

It will not be superfluous to take care of strengthening the brakes, it is recommended to replace the standard brakes with disc counterparts.

In addition, it is worth changing the factory tires, especially if your car has tires. domestic production. It is better to choose "classic" tires, although it all depends on your preferences - low-profile and wide tires can add handling, but reduce comfort.

Which rubber to choose depends on the budget, but it is better that it be foreign-made. After carrying out all the above changes, it is imperative to make wheel alignment. Subject to all the rules and the availability of the necessary equipment, suspension tuning can be done by hand.

It must be said right away that the front suspension of the VAZ-2107 is of a double-lever type, like on most rear-wheel drive cars. It is necessary to check from time to time technical condition all suspension units, as this affects the normal handling of the vehicle, as well as the comfort of the driver and passengers. Unfortunately, the quality of many components leaves much to be desired, so any element can unexpectedly fail. All work on checking and replacing suspension elements can be easily performed independently. True, for diagnostics, for example, it is best if there is an inspection hole in the garage or a flyover.

Suspension diagnostics

And now how to make technical inspection car, or rather its suspension, for troubleshooting. First of all, take a close look at the tires. Wear should be even. If the rubber began to wear out more on one side and less on the other, then the wheel alignment is clearly broken. Moreover, uneven wear tires indicates that there is a breakdown in the steering rods. Then you need not to repair the front suspension of the VAZ-2107, but to replace the steering.

Then you need to check the clearance in each of the front wheels. This must be done with the vehicle on a level surface. It is necessary to take hold of the wheel, or rather, its upper part, and then sharply pull it towards you. If the play in the bearings is very large, then you will hear characteristic knocks. Please note that the VAZ-2107 car has tapered bearings. They should have very little play. If the adjustment of the bearing did not help, then it will need to be replaced.

Checking shock absorbers

If the front shock absorbers fail, they must be replaced. In the presence of oil smudges or deformations on the body, new ones must be installed. Please note that a broken shock absorber cannot absorb all the vibrations of the car body while driving. In this case, the front suspension of the VAZ-2107 will not work correctly. Before starting repairs, you need to carefully check the shock absorbers to fully verify that they are malfunctioning. To check how well the front shock absorbers work, you need to carefully, trying not to damage the fender, put pressure on the front of the car.

If the shock absorbers are fully functional, then the body will immediately return to its original state. If the body continues to jump on the springs, we can conclude that there is a malfunction of the shock absorbers. It does not matter if one or both shock absorbers are broken, they only need to be replaced in pairs. It is worth noting that it is necessary to install new ones if there is an oil leak from the shock absorber cartridge. In this case, only the repair of the VAZ-2107 front suspension will help.

Removing shock absorbers

First, open the hood, unscrew the nut, with which the stem is attached to the car body. After unscrewing the nut, remove the washer and rubber gasket. Please note that the shock absorber rod must be held with a 6 key. But you can also use a special tool. After that, unscrew the two nuts that secure the levers. The shock absorber is pulled down. Complete replacement front suspension VAZ-2107 is not required.

Note that on a flat surface it will not be possible to remove it, even if the stem is completely recessed. It is necessary to slightly raise the entire side of the car on which the repair is being carried out. But it is most convenient, of course, to do all the work on a lift or a viewing hole. After removing the shock absorber, it is necessary to unscrew the nut, which is used to fasten to the bracket. This bracket is installed on a new shock absorber.

Installing a new shock absorber

Next, proceed to the installation of a new suspension element. In fact, all work is done in the reverse order. First, a bottom cushion made of rubber is put on the stem. Then the shock absorber body is installed in its place through a special hole in the lower arm. The rod must be fully extended and passed through the hole in the body. This is how the front suspension of the VAZ-2107 is easily repaired. The price of one shock absorber is an average of 900 rubles.

After that, you need to install a rubber cushion and a washer. You are baiting a nut. At the bottom, tighten the nuts securing the bracket to the lower arm. After that, tighten the nut on the stem until it stops. The installation of the new shock absorber is completed, similarly, the repair is carried out on the other side of the car.

Please note that a transverse rod is attached to it. This is what the front suspension diagram of the VAZ-2107 looks like. To make repairs, you need to have heads for 22 and 19, a spring puller will also come in handy. First, remove the wheel and remove the spring along with the shock absorber. The lower ball joint is detached from the wheel hub and completely removed. After that, using a 22 wrench, it is necessary to unscrew both nuts that fasten the lever to the car body.

Removing the lever

Using a 19 wrench, unscrew the nuts securing the transverse link to the suspension arm. Only after that it is necessary to move the axle with the help of a mounting blade and completely remove the lever. Please note that under the axle on which the suspension arm is mounted, there are special washers. With their help, the camber of the wheels is adjusted. Installing a new lower arm is done in reverse order. Be sure to install new nuts. Using a puller, the silent blocks are pressed into the new lever. That's all, the front suspension of the VAZ-2107 has been restored, now it will serve for quite a long time.
