The shock absorber is checked by hand.
Stretch and remove shock absorber.
The shock absorber should be uniformly hard to remove along the entire length of the piston stroke and easily return to its original position.
A defective shock absorber can also be recognized by noise during movement.
If the shock absorber functions flawlessly, small traces of oil are not a reason to change it.
If there is significant oil leakage from the shock absorber, it should be replaced.
