2.1

Leaking shock absorbers

Shock absorbers are often replaced because of externally visible
leakage. Inspections on the test rig and in the vehicle have shown
that in the majority of cases this replacement is not justified.
Slight loss of fluid ("sweating") at the piston rod seal is not a rea‐
son for replacing a shock absorber. A shock absorber with slight
fluid leakage can be accepted as "OK" under the following con‐
ditions:
♦ Fluid seepage (as shown in the shaded part of the illustration)
is visible, but the fluid is dull and possibly dried by dust.
♦ The fluid seepage extends only from the top shock absorber
seal (piston rod oil seal) down to the bottom spring plate
-arrow-.
2.2

Noisy shock absorbers

Shock absorbers are often replaced because of noises (rumbling,
etc.) experienced by the customer. Inspections on the test rig and
in the vehicle have shown that in approx. 70 % of these cases
there is no case for complaint. The replacement was not justified.
In the case of complaints regarding rumbling or knocking noises
please proceed as follows.
– Carry out a road test with the customer - if possible on a dry,
uneven road - to establish when, where and how the noises
occur.
Note
These noises are only very rarely caused by the shock absorbers.
