Removal Procedure

Notice: 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.

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

  3. Align the shock absorber with the mounting holes in the lower control arm.
  4. Notice: Refer to Fastener Notice in the Preface section.

  5. Install the shock absorber bolt (2) and nut (3).
  6. Tighten
    Tighten the nut to 80 N·m (59 lb ft).


    Object Number: 477707  Size: SH

    Important: The upper insulators are substantially larger that the lower insulators. The upper insulator (1) must be installed above the shock mounting bracket on the frame. The plastic pilot ring (2) will assist the alignment of the insulator.

  7. Install the upper insulator to the shock absorber.
  8. Install the nut to the tennon end. Do not tighten the nut.
  9. Support the lower control arm at curb height.
  10. Hold the tennon end with a wrench while torquing the nut.
  11. Tighten
    Tighten the nut to 20 N·m (15 lb ft).

  12. Lower the vehicle.
