Allow the rear axle to hang freely until the shock absorbers finish venting through the compressor. Support the rear axle with a floor jack to prevent it from dropping when the shock absorbers are disconnected.

During installation, ensure all air is expelled from a new shock absorber (for 2002 and earlier models), install all bushings and grommets in the order of removal, and use 5116-18 locknuts on the self-tapping bolts if the threads in the lower control arm are stripped or damaged. Tighten all fasteners to the specified torque, with locknuts torqued to the same specification as the bolts.

If the vehicle continues to move up and down or fails to return to its original position, a worn or weak shock absorber is likely the reason.

Raise the vehicle, support it securely on jackstands, and check the shock absorbers for evidence of fluid leakage. A light film of fluid is generally not a concern. If leakage is noted, replace the shocks as a set.

For 2003 and later models, remove the three shock absorber upper mounting nuts, the brake caliper, and the brake disc. Additionally, remove the upper and lower stabilizer bar links. Remove the upper balljoint nut and separate the control arm from the steering knuckle. Finally, remove the lower mounting bolt and the shock absorber/coil spring assembly from the front end of the vehicle.
