Shock Absorbers, Checking When Removed

Versions with coil springs

Defective shock absorbers are noticeable when driving due to loud rumbling noises - a result of wheel hopping - especially on poor stretches of road. Moreover, they can be recognized by a large loss of oil.

TIP:

Shock absorbers are maintenance-free, shock absorber oil cannot be filled.

A removed shock absorber can be checked by hand as follows:

-- Push the shock absorber together by hand.

• The piston rod must move with even resistance throughout the entire stroke and without jerking.

-- Release the piston rod.

• For shock absorbers with sufficient gas pressure, the piston rod returns automatically to its starting position.

TIP:

• If this is not the case, the shock absorber does not necessarily need to be replaced. As long as there is not a large loss of oil, the effectiveness corresponds to that of a standard shock absorber.
• The damping function is also completely available without gas pressure, as long as there is no large loss of oil. However, this can increase the noise level.
