6) Degradation of Damping Performance
It is impossible to verify the correct damping characteristic of a shock
absorber without a dynamometer. In the field, the following, more practical
test can help to identify a shock, which is suspected to have failed:
1) Conduct test few minutes after operating the vehicle
2) Touch a metal element of the chassis to determine a reference
temperature
3) Carefully touch the shock reservoir tube (lower tube, smaller diameter)
on either side of the same axle to measure temperature of shock
absorbers
4) Both shocks should be
-
warmer than the original reference point
- similar in temperature
5) A cool or significantly colder shock absorber likely is a failure and
needs to be replaced
6) After removal from the vehicle, the following may hint to the cause of
failure:
-
Manually stroke shock several times in vertical position:
no or delayed resistance would indicate a loss of damping force.
- Shake shock upside down: rattling would indicate a broken internal
component
7) A final determination can only be made by the manufacturer, using a
dynamometer
Other indicators of damping force degradation include:
a) ride deterioration
b) deteriorated rubber attachments
c) uneven tire wear („tire cupping“)
d) excessive vibrations and premature wear on other vehicle components
EFFECT : Reduced ride control, comfort and safety
ACTION : Replace shock absorber
