Stabilizer and its features
The anti-roll bar is one of the most important elements of a car's suspension. It helps with movement so effectively that if it stops performing its functions well enough, it is immediately noticeable. The main features of the rear stabilizer are the following:
- improves the running of the car;
- prevents rolls;
- prevents accidents.
Anti-roll bar
The rear anti-roll bar on classics really improves the ride of the car, although many drivers say that installing it is useless. In fact, if you ride with it for a while and then take it off, you can feel a big difference. The ride of the car will be less smooth, the driver will have to hold the steering wheel more tightly. With the front stabilizer you can feel the same thing, but in the case of the rear model the stability will be felt much more effectively.
Rear anti-roll bar
In addition to all this, the rear stabilizer on the classic actually works more effectively with rolls. The roll itself extends not only to the front of the car, and only one stabilizer has to fight it. To avoid all this and make the car feel more confident while driving, install a rear one.
Lateral roll
Do not forget that traffic stabilization is the key to safety. The driver may be in a different state behind the wheel - relaxed or more tuned to driving. In the first case, it will not always be possible to hold the steering wheel in extreme situations, which can lead to you falling into a snowdrift or into another car. The more systems a car has that help keep it moving, the safer it will be for the driver.
Stabilizer's pole
It should also be noted that there are disadvantages to the rear mechanism. The stabilizer will also have to deal with the stand, which constantly needs to be changed. This process does not take much time, but it needs to be done regularly, depending on the situation. How often it needs to be changed depends on the driver’s driving style. If the driver is a true master of his craft, it will not be difficult for him to hold the steering wheel, which means he does not need a stabilizer at all. With such driving, the struts will wear out very quickly, and the constant grinding will become very annoying over time.

Let's summarize - the stabilizer for the classic VAZ 2107 is an extremely controversial tuning element. On the one hand, it increases the stability of the car, but on the other hand, it reduces cross-country ability and driving comfort. However, it has one undoubted advantage - ease of maintenance. Even a novice car enthusiast can cope with this. After all, the only part of the SPU that is subject to rapid wear is the bushings, replacing which will not be a problem for a person who has at least once held a wrench with a mounting blade in his hands.
When do you need to change struts?
If the driver still decides to install a rear anti-roll bar on a classic, he will have to deal with the struts in any case. If the device is installed for the first time, the car owner simply does not know how to determine that his rack is no longer working. There are several ways to figure this out:
- grinding and crashing;
- severe drifts;
- the lubrication has run out.
Wear of the stabilizer strut
The first thing the driver may notice when the struts are worn out is a grinding and rattling noise. You can feel it when turning and drifting. This is such a unique sound that it is difficult to compare with anything. The sound appears only when it is completely worn out; initially there is no noise in this area. If you hear a rumble, the struts definitely need to be changed.
Important: In order not to be left guessing, the driver can not focus on the rumble, but independently touch the rack and feel the vibration with the rumble. To do this, your friend must pull the steering wheel to the side.
Checking the stabilizer strut
Since the stabilizer is connected to the car's suspension, it transmits information that the car has gone into a skid and a roll has appeared. All this information passes through the strut, as it performs an important function - it connects these two suspension elements. If the strut is worn out, the stabilizer stops performing its function and the driver experiences strong skidding when turning.
Car suspension
The stand can also be untwisted. To do this, you will need a jack to raise the rear of the car. The element is removed, the hinge is untwisted so that it is possible to get to the boot. There should be lubricant under it, and if the strut is worn out, there will be dirt mixed with lubricant residues under the boot.
Purpose, design and principles of operation of the VAZ 2107 stabilizer
It has already been written above that the SPU is one of the important parts of the car. But why? The answer is simple - thanks to it, driving improves significantly, becoming more comfortable. This device makes it possible to keep the chassis tilt under control without increasing the pressure on the camber of the rear wheels.
The increased control over the vehicle on sharp turns is especially noticeable.
Thanks to the stabilizer, it will be possible to enter such turns at higher speeds without the risk of capsizing.
The roll bar SPU looks like a C-shaped hose that is installed next to the axle. The stabilizer is mounted on brackets with rubber bushings inside.
It is worth noting that the VAZ 2107 stabilizer bushing is the weakest point in the design and breaks most often.
The stabilizer works on the principle of distributing the load between two suspensions.
Diagnostics
A breakdown can occur for a variety of reasons, so it is impossible to determine the exact time of full operation without breakdowns. Basically it all depends on the operating conditions. For example, if you often drive off-road, the stabilizer will break down often.
Basically, the SPU is checked during annual maintenance, but no one bothers you to do it yourself at any time.
First you need to remove the wheel. After this, use the steering wheel to make a maximum turn in any direction and shake the “bare” stand from side to side with your hand, grasping the middle third. If there are faults, looseness will be noticeable.
Signs of a broken rear stabilizer
The most common signs of failure are:
How should the stabilizer be positioned?
A correctly installed SPU should twist when the wheels turn.
Therefore, on passenger cars it is strictly forbidden to weld to the frame, since there must always be an intermediate link between it and the wheel. For example, in the VAZ 2107 bushings act as such a link. It is not recommended to use a stabilizer without them.
Causes of creaking stabilizer bushings
Drivers most often complain about bushings creaking either in cold or dry weather. But these are not the main factors and each driver may have his own reasons for this problem. They are individual for everyone. Main reasons:
Before replacing the anti-roll bar, you need to figure out what the problem is. Most often you just need to replace the rubber bands.
Why does the stabilizer bushing squeeze out?
In fact, the bushing is quite gentle to use. It can wear out pretty quickly. This mainly happens in winter. In cold weather, the bushing freezes, which can cause cracks to appear on it. Various reagents that are used to sprinkle roads during icy conditions can also play a role in this.
If the driver did not notice the problem in time, the cracks continue to grow. Because of this, the bushing begins to lose its elasticity. And so, at the next turn, it can simply be squeezed out of the eyelet. It is no longer possible to return it back - it is too worn out and will not be able to perform its direct functions.

After this, when entering a turn, the motorist may hear a creaking and grinding sound. The vehicle's handling will also decrease.
About double stabilizers
As the name suggests, there are two rods in this stabilizer. But such a device is installed only on the front wheels. Basically there are no fundamental differences.
Thanks to this SPU device, the stiffness of the suspension will increase significantly, which on the one hand is good, but on the other hand, some problems may arise. The fact is that on the classic VAZ 2107 the two front wheels operate independently of each other - that is, if the left front wheel lifts, the right one does not. But due to the installation of a double stabilizer, everything will change - the suspension will become semi-independent and the steering will become much stiffer, and the traction will become worse.
Therefore, before purchasing and installing a double SPU, you need to think carefully - either comfortable driving and good cross-country ability, or no roll.

You can make the VAZ 2101 - 07 more stable and maneuverable in other ways. You can replace the springs with stiffer ones. Of course, the cost of four springs will not be small. The time spent replacing them or the cost of replacing the springs, which will already result in a certain amount. And the result?
The result in practice is this. We got a tough car that handles well when cornering, but as soon as you hit an accordion or an unimportantly repaired road surface, it clearly loses to the soft suspension, which quietly absorbs bumps. Problems begin with a stiff suspension. The car holds the road worse on uneven surfaces. The butt is pulled to the side. When turning with uneven road surfaces, it skids. The service life of suspension and body parts is reduced. This is an ideal option for transporting potatoes from the dacha.
Replacing shock absorbers with double-sided ones. The cost of four double-sided shock absorbers is a round sum. For this amount we get the following behavior of the car on the road. The car becomes noticeably more maneuverable, but on long turns, the car still falls on its side as before. In this case, centrifugal forces do not work to their advantage. Comfort is already lost on uneven surfaces. In turns, accordion skidding is possible, because Double-sided shock absorbers do not allow the wheel to instantly react to irregularities in the form of a wave. The wheels freeze, at certain moments the grip on the road surface is lost, and the car pulls to the side.
I don’t want to say that the two currently popular options are full of shortcomings; some are quite happy with this option. But why lose dental fillings and blow out your brains when there are more humane ways to achieve better car behavior on the road? The Virage body stabilization system is a clear confirmation of this. The car's suspension remains comfortable. And it will no longer be possible to transfer it, only with a fool... Installed in five minutes. Maintains horizontal stability of the vehicle when maneuvering, cornering, sharply avoiding uneven surfaces, etc. A soft suspension is less prone to breakdown, because the transmitted force of one side to the other dampens the impact by redistributing the force across two axles (in the case when the impact falls on one wheel).
