Checking shock absorbers

Usually, shock absorbers do not fail suddenly, their effectiveness weakens gradually, to which they imperceptibly get used. The rule of thumb is that after two sets of tires worn out, stock shock absorbers have only 50% of their original efficiency and are therefore ripe for replacement.

It is not possible to make an accurate diagnosis by the known «rocking method» a standing car, in which the car is rocked by the wing at the corresponding shock absorber and then suddenly released. The springing motion must be damped immediately. So you can only determine a completely failed shock absorber.

A more accurate picture of the state of the shock absorber will give a special test stand. From the diagram, you can determine the performance of the shock absorbers. These test stands are available in car clubs for use by caravaners, as well as in some TU$V workshops and testing laboratories.
