REMOVAL & INSTALLATION



See Figures 1, 2 and 3

  1. Raise and support the rear of the vehicle safely using jackstands. Support the rear axle securely using jackstands or a floor jack. The axle must be supported to prevent overextension and damage to the brake lines once the shock is removed.
  2. If equipped, disconnect the automatic level control air lines from the shock absorber.
  3. Remove the shock absorber-to-frame retainers at the top of the shock.
  4. Remove the shock-to-axle retainers at the bottom of the shock.
  5. Remove the shock absorber from the vehicle.

To install:
  1. Position the shock in the vehicle and loosely install the upper mounting fasteners to retain it.
  2. Align the lower-end of the shock absorber with the axle mounting, then loosely install the retainers.
  3. On 1994 models, tighten the upper shock absorber retainers to 17 ft. lbs. (23 Nm). Then tighten lower shock absorber fastener to 47 ft. lbs. (64 Nm).
  4. On 1995 models, tighten the upper shock absorber retainers 22 ft. lbs. (30 Nm). Then tighten the lower shock absorber fastener to 73 ft. lbs. (100 Nm).
  5. On 1996-98 models, tighten the upper shock absorber retainers 22 ft. lbs. (30 Nm). Then tighten the lower shock absorber fastener to 62 ft. lbs. (84 Nm).
  6. On 1999 models, tighten the upper shock retainers to 18 ft. lbs. (25 Nm). Tighten the lower shock retainers to 62 ft. lbs. (84 Nm) on pick-up and two door utility models and 74 ft. lbs. (100 Nm) on four door utility models.
  7. If equipped, attach the automatic level control air lines to the shock absorber.
  8. Remove the jackstands and carefully lower the vehicle.
