Guideline to Evaluate Warranty Claims
Heavy-duty Shock Absorbers
“Misting“
OBSERVATION:
A precipitation of oil mist on
the outside of the shock is
visible.
Carefully touch shocks with dry
finger. (Use caution: shocks
may be hot!) If the finger
remains dry, the shock is not
leaking.
If in doubt, wipe shock clean
and check again after a few
days of operation.
CAUSE:
Oil vapor is necessary to
lubricate the rod seal. At high
operating temperatures this
results in oil mist and
precipitation.
EFFECT:
none
ACTION:
none
2) “Misting“
Appearance might be deceptive. A certain degree of vapor is normal and actually
necessary for lubrication of the rod seal.
The inspection must not be conducted after drive in wet weather or a vehicle wash.
Shock needs to be free from water.
