Shock Absorbers, Leaking
Shock absorbers are frequently rejected and exchanged because of leaks. Examinations on the test stand and on the vehicle have shown that the replacement of a large number of rejected shock absorbers was not justified.
Slight leaking of oil ("sweating") at piston rod seal is no reason to replace a shock absorber. A shock absorber damp with oil is OK under the following circumstances:
- Oil leak (shown screened in illustration) is visible, but dull, matte and possibly dry from dust
- Oil excretion extends from upper shock absorber connection (piston rod oil seal) no further than lower spring plate -arrow-
