The simplest, fairly quick and not so expensive way to get general information about the effectiveness of the suspension is to stop by a diagnostic stand, take measurements and listen to the verdict.
Another question is how precisely the verdict will apply directly to shock absorbers. The fact is that in the case of various kinds of “shaking” (of which there are more and more recently), the presence of at least one faulty element (not necessarily a shock absorber) will significantly affect the final results of the efficiency indicator. In addition, the algorithms by which the performance of the suspension are assessed differ, and diagnostics of one car on different stands can lead to the fact that the data obtained on the condition of the suspension may differ.
Shock absorbers for the VAZ 2107 - tips for diagnosing and repairing the chassis
How to check shock absorbers on a VAZ 2107 and determine their condition
The VAZ 2107 was very popular at one time, and is still in some demand due to its low price, but its reliability is far from the best. Owners often have to carry out repairs, so the sale of spare parts for the VAZ 2107 has become a good business for some auto shops.
Relatively often, motorists also repair the chassis of the VAZ 2107. It should be noted that, as a rule, shock absorbers in the chassis fail and auto mechanics recommend changing them every 40 thousand km, regardless of whether they have leaked or not. If you do not make this replacement, then certain difficulties may arise with driving the car, and its braking distance will be increased. It is advisable to change shock absorbers on a VAZ 2107 on a lift or inspection pit, but in emergency situations you can get by with just a jack.
A signal to replace the front shock absorbers on the “seven” may be the presence of oil leaks on the body or deformation of the shock absorber. To make sure that this device is faulty, you need to sharply press on its hard part and release it; if the body sank and returned to its original position without vibrations of the suspension, then the shock-absorbing part is in perfect order. But when the body continues to oscillate, this will indicate a malfunction of the shock absorber and the need to repair the chassis of the VAZ 2107. Experts advise contacting service centers to replace the shock absorbers.
The rear shock absorbers on a VAZ 2107 also need to be changed in case of a fluid leak. To check their condition, you need to sharply press on the rear wing of the car; if the shock absorber is in order, then the suspension should slowly sag, and then slowly return to its previous position.
The VAZ seven is technically simple, but many negative factors, including bad roads, lead to failure of shock absorbers, the suspension as a whole and other equipment. Today there is no consensus on which shock absorbers to install on this car, but still, experts advise buying spare parts in reputable stores. Before buying spare parts for the VAZ 2107, consider your driving style. For example, if shock absorbers are purchased, then speed fans can choose hard models, while soft shock absorbers are more suitable for lovers of quiet movement.

Shockabsorber-replacement-14_
There are known cases when, when diagnosing a car on a “shaky ride” with a working suspension and recently replaced shock absorbers, the data obtained indicated low residual effectiveness of the suspension. But during the “test drive” the car behaved perfectly. The reason is that the stand was not designed for more “hard” settings of the tuning series shock absorbers compared to the characteristics of the original products, as a result - a wrong verdict. Well, that happens.
A very important point! The final indicators may be influenced by such parameters as tire pressure, vehicle loading during diagnostics, small deviations from a straight line when driving to the stand (appearance of a deviation angle from the longitudinal axis), accidental installation of the vehicle on the handbrake, uneven loading of the vehicle during diagnostics, etc. .d. It will be a real pleasure for a careless repairman to “cheat” a client out of the cost of new shock absorbers, so that in the meantime, as if by accident, pump up his flat tire...
Replacing rear shock absorbers
Replacing the rear shock absorbers is somewhat simpler than the front ones, but we will need the same equipment: a 19 mm wrench, a jack, a new unit.
- We jack up the rear of the car and remove the rear wheels one by one.
- Take a 19 mm wrench and unscrew the rear axle bolt. In this case, you need to support the bolt with a similar 19mm wrench.
- Remove the bolt and bushings.
- Using the same 19mm wrench, remove the nut holding the shock absorber rod and dismantle the shock absorber itself.
The assembly has been removed, now we proceed to install the new part, which is carried out like any installation in the reverse order of dismantling.
Conclusions?
There is no single known correct method for diagnosing shock absorbers. Each case has its own specifics. Bon Voyage!

Shock absorbers can be checked in several ways:
- Visual. If you find fluid leaks, then your shock absorbers are faulty, remove them from the VAZ 2101-2107 for repair or replacement, we recommend specialized workshops; — subjectively — If you notice while driving that the efficiency of vibration damping of the car is reduced or frequent hard shocks appear during rebound and compression (“breakdowns”) of the suspension, your shock absorbers are also not working properly, you need to remove them for repair or replacement. Also, a subjective express check of shock absorbers can be carried out, as shown in the photo, points 1-5; — the most correct thing would be to check shock absorbers on specialized stands (both shock absorbers installed on a VAZ 2101-2107 car and those dismantled).
1. Place the VAZ 2101-2107 car on a flat floor in the garage or a level area. The engine must be turned off and the gearbox must be in first or reverse gear. Do not use the handbrake.
2. Rock the car by the wing (angle) up and down with an amplitude of at least 45-50 mm. 3. At the lowest point, release your hands. 4. The shock absorber is working only if the VAZ 2101-2107 car made one upward oscillation, then half a downward stroke and stopped. 5. Next, repeat steps 2-4 for the remaining three shock absorbers. ¶
Features of replacing the shock absorber on a VAZ 2104
A lot of general materials have already been written about replacing shock absorbers, which offer repair algorithms. However, now we will also talk about more subtle things that will help you save not only time, but also money. First, before replacing the shock absorber, you need to dismantle the old one. There is nothing complicated about this. The fastening here is with two screws. It should be noted that the top bolt is welded in; there is no need to hold it. But the situation with the bottom bolt is different: it has a nut on one side, and the bolt head on the other. Therefore, you need to hold it on both sides.
The place is very dirty and wet as it is the bottom of the car. Threaded connections are susceptible to corrosion, so there is a chance that the nuts simply will not come off. Of course, you may get lucky and both bolts will come out easily. The top bolt must be unscrewed in any case. It will be more difficult with the bottom one, since even if the nut is unscrewed, it is not possible to unscrew the bolt - the tube put on it sours in the middle. However, if you still manage to unscrew this bolt completely without tricks, then you will save about 100 rubles. If you are less fortunate, the bolt will have to be cut off. Even after cutting the bolt, I was unable to knock it out of the tube. It's best to stock up on bolts in advance. When installing shock absorbers on a VAZ 2104, there is a small nuance. Keep in mind that shock absorbers from the VAZ 2101 and other “classics” are not exactly what you need, they will not fit. Here you need to use spare parts for the “four”. They are not suitable because their length is not very long.

Guarantee
1 year Description Shock absorbers VAZ 2101-2107 (these VAZ models have a more common name - “classic” ), like all shock absorbers produced by the SS20 company for other cars, have several versions: “Comfort”, “Highway” and “Sport” " The presence of different settings options allows you to choose shock absorbers that suit your driving style. The family of VAZ cars with a classic layout has earned a popular reputation as simple and fairly reliable inexpensive cars to operate. At the same time, the level of driving comfort and smooth ride also contributed to the love of our compatriots for the VAZ classics. But over the years that the family remained on the assembly line, both the speed of movement and the requirements for car handling increased. At the moment, we can say with confidence that in modern conditions, when driving both in the city and on the highways, cars of the VAZ 2101-2107 family are forced to reduce speed and do not provide an acceptable level of controllability and stability at speeds of even 90 km/h. Therefore, when developing and testing shock absorbers 2101-2107, the main attention was paid to improving the car’s handling while maintaining maximum comfort, and improving the car’s behavior on country roads. The shock absorber housing for the “classic” SS20 production was enlarged compared to standard shock absorbers, which made it possible not only to increase the oil volume, but also to use larger diameter pistons, which significantly reduced the specific loads on the elements of the valve system and increased their service life. Pistons with a “skirt” are used, providing excellent sealing and stability of shock absorber characteristics with an extended service life. The lower and upper silent blocks of the front shock absorber have an original design that is superior to the factory shock absorber for the VAZ 2101-2107 family in terms of reliability and damping capacity. Thus, the shock absorber for the “classics” (VAZ 2101, 2102, 2103, 2104, 2105, 2106, 2107) of the SS20 brand is a reliable design that will allow you to forget about a number of problems that arise when operating a car with standard shock absorbers. In addition, with SS20 products you will protect yourself from counterfeits: all SS20 products have branded packaging, stickers, and dot markings.

What are the consequences of a faulty shock absorber?
Shock absorbers (dampers) are devices that serve to dampen vibrations while a car is moving (damping) by converting mechanical energy into thermal energy. Shock absorbers operate in conjunction with such vehicle suspension elements as springs, springs, torsion shafts, cushions, etc.
Diagnostics of shock absorbers must be carried out systematically by the driver. Why, you ask, because MOT was passed, and everything was fine. Unfortunately, like everything in this world, shock absorbers tend to fail. And the sooner the driver notices a shock absorber malfunction, the less money will then be spent on restoring the consequences.
The most important thing is for you to remember that systematically checking the shock absorbers yourself takes a couple of minutes, and can save you from troubles with other car systems.
How to replace rear springs on a VAZ-2107
Over time, the elasticity of the metal decreases, the car sags, and in potholes the wheels begin to reach the wheel arch liners. It's time to replace the rear springs . The procedure is not complicated and a driver with minimal plumbing experience will be able to fix the problem on his own. This article is suitable for owners of all “classic” VAZs from 2101 to 2107 . Sometimes replacing the spring spacers with thicker ones helps. They are available in three versions with different thicknesses. If the springs haven’t burst, then the Zhiguli car is still ok with inflated spacers.
