SHOCK ABSORBER REPLACEMENT

Removal Procedure

1. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.

NOTE:

The front shock absorbers of the vehicle are multifunctional. In addition to
contributing to a smooth ride they also provide the only stop to the front
suspension when fully extended. Therefore, when servicing the shock absorber,
service replacement shock absorbers must be equivalent to original shock
absorbers in both extended length and strength. Use of shocks not complying
to original equipment or strength could result in suspension over-travel or
shock breakage. Suspension over-travel may result in suspension component
breakage.
