INSPECTION
1. Inspection of shock absorber ASSY FR LH
(1) Operation inspection of shock absorber ASSY FR LH
(a) Press the shock absorber ASSY FR LH to the lowest position while holding it up and let it extend on its own. Repeat the process four times or more.

Criteria
: When it is compressed at a certain speed, the heaviness of each stroke is consistent, and it does not make any abnormal movement or sound. Also, when it extends, it returns to its original length at a consistent speed without any abnormal sound.
NOTE:
If defective, replace the shock absorber ASSY FR LH with a new part.
