Exploded View





Removal

1. Raise and support the vehicle Service and Repair.

2. Remove the rear wheel.

3. Remove the wire guide grommet (A) from both sides of the axle beam.






4. Position the floor jack under lower spring seat (A) on both sides of the axle beam (B). Raise the floor jack until the suspension begins to compress.





5. Remove the damper mounting bolt (C) from both sides.

6. Remove the access panel (A) from the cargo area side trim.






7. Remove the self-locking nut (A) while holding the damper shaft (B) with a hex wrench (C).





8. Remove the damper mounting washer (D) and the damper rubber mount (E) from the top of the damper.

9. Compress the damper unit (A) by hand, and remove it from the vehicle.

NOTE: Be careful not to damage the body.





10. Remove the damper rubber mount (B).

Inspection

1. Install the flange nut on the damper shaft end, and set the socket wrench and T-handle on the nut.

2. Compress the damper assembly by hand, and check for smooth operation through a full stroke, both compression and extension. The damper should extend smoothly and constantly when compression is released. If it does not, the gas is leaking and the damper should be replaced.





3. Check for oil leaks, abnormal noises, and binding during these tests.

Installation

1. Install the damper rubber mount (A) onto the damper unit. Position the damper assembly (B) between the body and the axle beam.

NOTE: Be careful not to damage the body.






2. Position the floor jack under lower spring seat (A) on both sides of the axle beam (B).





3. Slowly raise the jack until you can align the bolt hole with the holes in the axle beam and the damper (C), then loosely tighten the new damper mounting bolt (D) on both sides.

4. Raise the rear suspension with the jack until the vehicle just lifts off of the lift, then tighten the damper mounting bolts to the specified torque.

5. Install the damper rubber mount (A), the damper mounting washer (B), and the new self-locking nut (C) on the damper shaft (D).

NOTE: During installation, note the direction of the damper rubber mount and the damper mounting washer.






6. Tighten the self-locking nut (A) to the specified torque value while holding the damper shaft (B) with a hex wrench (C).






7. Install the access panel (A) on the cargo area side trim.






8. Install the wire guide grommet (A) on both sides of the axle beam.





9. Clean the mating surfaces of the brake drum and the inside of the wheel, then install the rear wheel.
