Removal Procedure

Caution: 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.
  2. Support the lower control arm with a safety stand.

  3. Object Number: 793302  Size: SH

    Object Number: 353965  Size: SH
  3. Install the shock absorber bolt (2) and nut (3) and tighten the nut to 80 N·m (59 lb ft).

  4. Object Number: 477707  Size: SH

    Note: The upper insulators are 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.

  5. Install the upper insulator to the shock absorber.
  6. Note: Do not tighten the nut.

  7. Install the nut to the tennon end.
