Rear Suspension

Spring - Coil









Removal

NOTICE: Suspension fasteners are critical parts because they affect the performance of vital components and their failure may result in major service expense. Install new fasteners with the same part number or an equivalent part if installation is necessary. Do not install a part of lesser quality or substitute design. Torque values must be used as specified during reassembly to ensure correct retention of these parts.

1. For reference during the installation procedure, measure the distance from the lip of the fender to the center of the wheel hub with the vehicle in a static level ground position.





2. WARNING: Before servicing a vehicle equipped with a fire suppression system, depower the system by following the procedure in Fire Suppression System. Failure to follow the instructions may result in serious personal injury Procedures.

With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to Jacking and Lifting Service and Repair.

- Install new insulators, if necessary.

2. Install the spring insulators on the springs.

3. Install the springs and the spring insulators in the vehicle.
- Make sure that the springs are correctly seated.

4. Raise the axle using the jack or jackstands.

5. Connect the shock absorbers to the axle and install new bolts and nuts.
- Make sure that the bolts are installed from the inboard side.

- Tighten the nuts to 90 Nm (66 lb-ft).

6. Connect the lateral arms to the frame and loosely install new bolts and nuts.
- Do not tighten at this time.

7. Using the jack, raise the suspension until the distance between the lip of the fender and the center of the wheel hub is equal to the measurement taken in the removal procedure.





8. Tighten the lateral arm-to-frame bolts to 90 Nm (66 lb-ft).

9. Lower the axle and remove the suitable jack or jackstands.

10. Connect the stabilizer bar to the stabilizer bar links in the following sequence.

1. Rotate the stabilizer bar onto the links and install the bushings.

2. Install the new nuts and tighten to 20 Nm (177 lb-in).

11. WARNING: If the vehicle is equipped with a fire suppression system, repower the system. For important safety warnings and procedures, refer to Fire Suppression System. Failure to follow these instructions may result in serious personal injury Description and Operation.
