Rear Suspension

INSTALLATION

1. Support the rear suspension crossmember with a transmission jack. Secure the crossmember to the jack.
2. Slowly raise the crossmember into mounted position using the transmission jack matching the crossmember to the marked locations on the body made during removal. As the crossmember is raised, guide the rear suspension components into place.
3. Install the four mounting bolts (rear bolts have stud heads) securing the crossmember to the body. Tighten the crossmember mounting bolts to 95 Nm (70 ft. lbs.).
4. Position the crossmember reinforcement brackets (one each side of vehicle) over the crossmember rear mounting bolt head-studs and install the mounting nuts, but do not tighten at this time.
5. Install the mounting screws securing the crossmember reinforcement brackets to the body. Tighten the screws to 55 Nm (41 ft. lbs.).
6. Tighten the mounting nuts securing the reinforcement brackets to the rear crossmember mounting bolts to 50 Nm (37 ft. lbs.).
7. Remove the transmission jack.




8. On each side of the vehicle, position the upper control arm (5) and install the bolt (1) and nut (2) securing the arm to the crossmember. Do not tighten either upper control arm mounting bolts at this time.






CAUTION: When installing the cam bolt (4) and washer make sure the cams stay inside the abutments built into the crossmember. Failure to do so can damage the abutments and make toe adjustment difficult.

9. On each side of the vehicle:
a. Position the toe link (2) and install the cam bolt (4) from the front through the crossmember and link. Match the cam on the bolt to the marks made during removal or position the top of the cam to the 12 O'clock position if not available.
b. Install the cam washer (1) and nut (3) securing the toe link (2) to the crossmember. Do not tighten at this time.





10. On each side of the vehicle, position the lower control arm (3) and install the bolt (6) and nut (4) securing the lower control arm to the crossmember (5). Do not tighten nut and bolt at crossmember or knuckle at this time.






NOTE: When installing the stabilizer bar on a vehicle with all-wheel-drive, position the bar so that the bar loops over the axle half shafts once installed, not under the axle half shafts.

11. Position the stabilizer bar (3) on the rear crossmember.

CAUTION: Before installing the screws in the following step, it is especially important to clean the threads and apply Mopar(R) Lock AND Seal Adhesive or equivalent.

12. Install the two retainers (5 - right side shown) over the cushions at the mounting holes and install the retainer screws (1). Do not tighten the screws at this time.

CAUTION: Before installing the nut in the following step, it is especially important to clean the threads and apply Mopar(R) Lock AND Seal Adhesive or equivalent.

13. On each side of the vehicle, install the stabilizer link (4) upper stud in the end of the stabilizer bar (3). Install the nut (2) on the upper stud and while holding the stabilizer link stud stationary, tighten the nut to 48 Nm (35 ft. lbs.).
14. On each side of the vehicle, tighten the stabilizer bar retainer screws (1) to 25 Nm (18 ft. lbs.).






NOTE: Always install a new hub nut. The original hub nut is one-time use only and should be discarded when removed.

15. If equipped with all-wheel-drive, slide the half shaft into the hub and bearing on each side of the vehicle and hand-start the washer and hub nut (3) Support the shafts to keep them from overextending the joints.

16. If equipped with all-wheel-drive, install the rear driveline module. In place of using a drive-on hoist, place jacks under the outboard ends of the lower control arms and adjust the rear suspension height at the hub and bearings to simulate curb riding height. Removal Once the rear driveline module is installed, remove the jacks.




17. On each side of the vehicle, if equipped with load-leveling shocks, place a jack (2) against the lower shock eye and support the lower end of the shock assembly (1). Lift the shock assembly using the jack until the hole in the lower shock eye lines up with that in the lower control arm.





18. On each side of the vehicle, install the mounting bolt (4) and nut (1) fastening the shock assembly (2) to the lower control arm (3). Do not tighten at this time.





19. Position the four parking brake cable routing clamps along the front of the rear crossmember and install the screws. Tighten the screws to 6 Nm (55 in. lbs.).
20. Install the exhaust system. Exhaust Pipe - Installation.





21. On each side of the vehicle, attach the wheel speed sensor routing clamp (2) to the rear suspension crossmember (3) using the mounting screw (1). Tighten the mounting screw to 20 Nm (15 ft. lbs.).





22. While a helper applies the brakes to keep the hub (1) from rotating, on each side of the vehicle:
a. Tighten the hub nut (3) to 245 Nm (181 ft. lbs.).
b. Insert the cotter pin (2) through the notches in the nut and the hole in half shaft. If the notches in the nut do not line up with the hole in the half shaft, continue to tighten the nut until they do. Do not loosen the nut.
c. Wrap the cotter pin (2) ends tightly around the lock nut.





23. On each side of the vehicle, install tire and wheel assembly (1) Tires and Wheels - Installation. Install and tighten wheel mounting nuts (3) to 135 Nm (100 ft. lbs.).

24. Lower the vehicle.
25. Position the vehicle on an alignment rack/drive-on lift. Raise the vehicle as necessary to access mounting bolts and nuts.
26. Tighten the lower control arm mounting bolt nut at the crossmember to 105 Nm (77 ft. lbs.).
27. Tighten the lower control arm mounting bolt nut at the knuckle to 105 Nm (77 ft. lbs.).
28. Tighten the shock assembly lower mounting bolt nut to 99 Nm (73 ft. lbs.).
29. Tighten the upper control arm mounting bolt nut at the crossmember to 105 Nm (77 ft. lbs.).
30. Tighten the upper control arm mounting bolt nut at the knuckle to 105 Nm (77 ft. lbs.).
31. Tighten the toe link mounting bolt nut at the knuckle to 105 Nm (77 ft. lbs.).
32. Perform wheel alignment as necessary. Service and Repair





33. Once rear toe is set, while holding the cam bolt (4) head stationary, tighten the toe link mounting cam bolt nut (3) to 100 Nm (74 ft. lbs.).
