When are dampers leaky?
Apparently leaking shocks often don't indicate a defect, but are absolutely tight and functioning properly. A certain amount of “perspiration” is completely normal, and even necessary to lubricate the piston rod seal. Therefore never assess the dampers after driving in the rain. When you check them, they must be dry.
Here is the best way to do the job:
- Feel the damper with dry fingers.
- If your fingers remain dry, the damper is usually not leaky. If you have any doubts, thoroughly wipe the damper and check it again after a few days.
