Shock Assembly: Assembly

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.

1. Install the sleeve into the lower shock absorber rod isolator bushing. See Figure. Install the shock absorber rod lower isolator bushing and sleeve in the bottom of the upper (shock absorber/upper control arm) mounting bracket as shown in illustration. See Figure. From the top, install the shock absorber rod upper isolator bushing into the center of the upper mounting bracket over the sleeve protruding from the lower isolator bushing. See Figure. The smaller end of each bushing is to face away from the upper mounting bracket once installed.
2. Place the lower end (smaller diameter) of the coil spring in the spring compressor supported by the lower hooks, following the manufacturer's instructions. Position the coil spring lower end tip at the position it was at before coil spring removal from the compressor as noted in step  8 of DISASSEMBLY (Refer to SUSPENSION/FRONT/SHOCK - DISASSEMBLY) . Proper orientation of the spring in the compressor is necessary for proper alignment of all shock assembly components.
3. Place the dust shield and cup inside the coil spring. See Figure. Secure the lower shock rod bushing retainer washer over the cup.
4. Install the upper coil spring isolator on top of the spring matching the built-in step in the isolator to the tip of the coil spring.
5. Position the upper control arm ball joint so it lies directly below the front upper hook as shown in illustration, then install the upper (shock absorber/upper control arm) mounting bracket on top of the coil spring isolator placed on the coil spring. See Figure.
6. Position the upper hooks on top of the upper mounting bracket as shown in illustration. See Figure.
7. Compress the coil spring.
8. Install the lower spring isolator on the lower spring seat of the shock absorber. See Figure. When installing the spring isolator, be sure the isolator sets in the notch made for the lower coil spring end.
9. Install the jounce bumper on the shock rod. See Fig 1. Install the jounce bumper with the pointed end pointing downward.

10. Install the collar, undercut side facing down, on the rod of the shock absorber. See Fig 2. Be sure the collar is positioned squarely on the step of the shock absorber rod.

11. Install the shock through the bottom of the coil spring, then through the dust boot, cup and retainer washer until the lower spring seat contacts the lower end of the coil spring. The lower coil spring end should set into the notch of the shock absorber lower seat and isolator. Install the clamp temporarily securing the shock absorber to the coil spring. See Figure.
12. Install the upper shock rod bushing retainer washer. Make sure the concave side is facing up (curved outer edge up).
13. 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 45 N.m (33 ft. lbs.). See Figure.
14. Slowly release the tension from the coil spring by backing off the compressor drive fully. As the tension is relieved, make sure the upper mounting bracket, 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.
15. Install shock assembly on the vehicle. (Refer to SUSPENSION/FRONT/SHOCK - INSTALLATION)
