Removal & Installation
- Before servicing the vehicle, refer to the Precautions Section.
- Properly support the rear axle assembly.
- Disconnect automatic level control air lines from the shock absorber, if equipped.
- Remove shock absorber-to-frame retainers at the top of the shock.
- Remove shock-to-axle retainers at the bottom of the shock.
Remove shock absorber.
- Install the shock in the vehicle and loosely install the upper mounting fasteners to retain it.
- Align the lower-end of the shock absorber with the axle mounting, then loosely install the retainers.
- 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.
- If equipped, attach the automatic level control air lines to the shock absorber.
Testing & Inspection
Visually inspect the shock absorber. If there is evidence of leakage and the shock absorber is covered with oil, the shock is defective and should be replaced.
If there is no sign of excessive leakage (a small amount of weeping is normal) bounce the van at one corner by pressing down on the bumper and releasing it. When you have the van bouncing as much as you can, release the bumper. The van should stop bouncing after the first rebound. If the bouncing continues past the center point of the bounce more than once, the shock absorbers are worn and should be replaced.
