Suspension Strut / Shock Absorber: Component Tests and General Diagnostics
Checking After Removal
Shock absorbers, checking while removed
Faulty 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.
Note:
^
Shock absorbers are maintenance-free, shock absorber oil cannot be topped off.
A removed shock absorber can be checked by hand as follows:
-
Press shock absorber together by hand.
^
Piston rods must move smoothly and with uniform difficulty over the entire range
-
Release piston rods.
^
On shock absorbers with sufficient gas pressure, piston rods return to initial position by themselves.
Note:
^
If this is not the case, shock absorber must be replaced. As long as there is no large loss of oil, the mode of operation corresponds to that of a
conventional shock absorber.
^
The damping function is also completely available without gas pressure, as long as there is no large loss of oil. However, noise may increase.
