Rear

The shock assembly must be removed from the vehicle for it to be disassembled and assembled. Refer to REPLACEMENT for the required procedure.

For the disassembly and assembly of the shock assembly, use strut spring compressor Pentastar Service Equipment (PSE) tool W-7200, or the equivalent, to compress the coil spring. Follow the manufacturer's instructions closely.

DISASSEMBLY
1. If both shocks are being serviced at the same time, mark the coil spring and shock assembly according to which side of the vehicle the shock was removed from, and which shock the coil spring was removed from.

Lower Hooks And Clamp:




Upper Hooks Positioned:





2. Position the shock assembly in the strut coil spring compressor following the manufacturer's instructions. Set the lower hooks and install the clamp on the lower end of the coil spring, so the shock is held in place once the shock shaft nut is removed. Lower the upper hooks and position them on the coil spring near the top.

WARNING: DO NOT REMOVE THE SHOCK ROD NUT BEFORE THE COIL SPRING IS COMPRESSED. THE COIL SPRING IS HELD UNDER PRESSURE AND MUST BE COMPRESSED, REMOVING SPRING TENSION FROM THE UPPER MOUNTING BRACKET BEFORE THE ROD NUT IS REMOVED.

3. Compress the coil spring until all coil spring tension is removed from the upper mounting bracket.

Retainer Nut Removal/Installation:





4. Hold the shock rod from rotating using special socket Snap-On A136, or an equivalent, and remove the retainer nut.
5. Remove the upper shock rod bushing retainer washer from the shock rod.
6. Remove the upper shock mount and the rod isolator bushings as an assembly from the rod of the shock absorber.

Upper Coil Spring Isolator, Washer And Dust Boot:





7. Remove the upper coil spring isolator from the top of the coil spring.
8. Remove the lower shock rod bushing washer from the top of the dust boot and shock absorber rod.
9. Remove the dust shield and cup as an assembly from the shock absorber rod by pulling both straight up and off the shock rod.
10. Remove the clamp from the bottom of the coil spring and remove the shock absorber, lower spring isolator, jounce bumper, and collar out through the bottom of the coil spring.

Shock Absorber Jounce Bumper And Collar:





11. Remove the jounce bumper and the collar from the rod of the shock absorber.

Lower Coil Spring Isolator:





12. Remove the lower coil spring isolator from the lower spring seat on the shock absorber.





13. Remove the upper shock rod isolator bushing and sleeve from the upper shock mount.





14. Remove the lower shock rod isolator bushing from the upper shock mount.
15. Inspect the shock assembly components for the following and replace as necessary:
- Inspect the shock for any condition of rod binding over the full stroke of the shaft.
- Check the upper shock mount for cracks and distortion, and locating studs for any sign of damage.
- Check the upper and lower shock rod isolator bushings for severe deterioration of the rubber.
- Check the upper and lower coil spring isolators for severe deterioration of the rubber.
- Inspect the dust shield for rips and deterioration.
- Inspect the jounce bumper for cracks and signs of deterioration.
- Inspect the coil spring for any sign of damage to the coating.
16. If the coil spring needs to be serviced, release the tension from the coil spring by backing off the compressor drive fully. Push back the compressor upper hooks and remove the coil spring from the compressor.

ASSEMBLY

Lower Hooks And Clamp:





1. If the coil spring has been removed from the compressor, place the lower end (smaller diameter) of the coil spring in the spring compressor supported by the lower hooks at the same position as in disassembly, following the manufacturer's instructions.

Upper Hooks Positioned:





2. Position the upper hooks of the spring compressor on the coil spring near the top as in disassembly.
3. Compress the coil spring enough to reinstall the shock absorber and upper mount.





4. Install the lower shock rod isolator bushing in the bottom of the upper shock mount. The smaller end is to be pointed away form the mount.





5. Install the upper shock rod isolator bushing and sleeve in the upper shock mount until seated into lower bushing. The smaller end of the bushing is to be pointed away from the mount when installed.

Lower Coil Spring Isolator:





6. Install the lower coil spring isolator on the lower spring seat of the shock absorber.

Jounce Bumper Installed:





7. Install the jounce bumper as shown on the rod of the shock absorber.





8. Install the collar on the rod of the shock absorber assembly with the undercut side of sleeve facing down. Push the collar down until seated on the step of the shock absorber rod.
9. Install the shock through the bottom of the coil spring until the lower spring seat contacts the lower end of the coil spring. Install the clamp temporarily securing the shock absorber to the coil spring.
10. Install dust shield and cup over the jounce bumper and onto the rod of the shock absorber.
11. Install the lower shock rod bushing retainer washer on the shock absorber rod.

Upper Coil Spring Isolator, Washer And Dust Boot:





12. Install the upper spring isolator on the top of the coil spring. The bottom of the isolator is contoured to fit around the inside diameter of the coil spring.
13. Install the upper shock mount bracket and rod isolator bushings as an assembly on the top of the rod of the shock absorber.
14. Install the upper shock rod bushing retainer washer. Make sure the concave side is facing up.

Retainer Nut Removal/Installation:





15. Install the shock assembly retainer nut. Hold the shock rod from rotating using special socket Snap-On A136, or an equivalent, and tighten the retainer nut using a crow foot wrench (on the end of a torque wrench and extension) to a torque of 55 Nm (40 ft. lbs.).
16. Position the upper shock mount so it's studs are in line with the bolt hole in the shock absorber lower bracket.
17. Slowly release the tension from the coil spring by backing off the compressor drive fully. As the tension is relieved, make sure the upper mount, isolator, and coil spring align properly. Remove the clamp from the lower end of the coil spring and shock. Push back the spring compressor upper and lower hooks, then remove the shock assembly from the spring compressor.
18. Install shock assembly on the vehicle.
