How to check the shock absorber?

Before checking the technical condition of the shock absorber, you need to learn simple truism for its operation. After a run of 40 thousand km. shock absorbers are subject to mandatory replacement, taking into account the state of our roads. There is an exception if the manufacturer gives a longer warranty on use.

Visual inspection

The wear of various parts of the shock absorber, whether its seals or valves for long periods of operation, is inevitable. So, how to check the performance of the shock absorber?

  • To begin, we test the performance of the shock absorber by simply rocking the body. To do this, push and release that corner of the body where the shock absorber is located. If the body oscillates no more than two times, then the shock absorber is normal.
  • Further pay attention to the wheels. If the tread wears unevenly, then this may also indicate a shock absorber failure. However, we must remember that this method of verification is not sufficiently reliable. And yet, how to check the operation of shock absorbers for sure? At first,the oscillation frequency depends on the state of the other numerous suspension assemblies; therefore, it is possible to identify a dead shock absorber in this way. Secondly, the vibrations that a car experiences on the road do not correspond to the amplitude and frequency of vibrations of our test. Therefore, if the test did not show any deviations in the operation of the shock absorber, then for a more accurate diagnosis, you must make sure that the shock absorber is in good condition at the service station.
  • The next step is a visual inspection of the shock absorber. This operation does not take a lot of time and money. A simple external examination reveals serious emergency faults, but unfortunately it is thus impossible to diagnose natural wear of the suspension.

Additional inspection

If during the inspection the shock absorber case is contaminated or has traces of an anti-corrosion preparation, then this seriously affects its service life, because during the intensive work of the suspension a large amount of thermal energy is released. And the pollution of the shock absorber prevents the dispersion of high temperatures in the housing.We also inspect the shock absorber for the presence of deformation in its body. Irregularities in the housing can create increased friction during the piston. Further pay attention to the piston rod, since the curvature of the stem can lead to jamming of the suspension while the car is moving, which is extremely dangerous for the life and health of the driver and passengers. If during the external examination of the shock absorber you find scratches, areas of corrosion, irregularities of the chrome plating, then all this can cause depressurization. Unfortunately, often due to unqualified installation, we can observe mechanical damage to the shock absorber. The leaked shock absorber cannot perform its functions, therefore it must be urgently replaced with a new one.

Diagnostics in car service

In order to better diagnose the shock absorber, you can use special equipment in the service station. How to check shock absorber on shaker? Testing on such equipment costs money, so pre-ask the mechanics the following questions. First, are the vibrator settings tuned to your car model or type of suspension? Second, is the age of the car taken into account in the diagnosis? If you have a serious accident, be sure to report it.If your suspension consists of non-original parts, this may also affect the test results. It would be useful to take into account the collapse, convergence and pressure in the wheels. If you ignore one of these questions, you risk getting incorrect diagnostic results, which means you will lose time and money.

How to check the rear shock absorbers? Sometimes during the operation of the car there is a feeling of strong side wind. And it blows you either into the oncoming lane or into a ditch at a time when there is complete calm on the street. This is a clear sign that the rear shock absorbers are in a very neglected state. In principle, the rear shock absorbers are inspected and diagnosed similarly to the front shock absorbers.

New shock absorbers also need to inspect for the presence of stains and deformation of the body.
