Turn off the air suspension and disconnect the height sensor. Support it on jack stands and let the rear axle hang free until the shock absorbers vent. Compress the shock to remove the inner insulator and washer. Remove the side trim panel from the trunk to access the upper mounting nut. Remove the lower retaining nut or bolt and the shock absorber. Before installing a new shock, expel all air by extending and compressing it. Insert the shock rod through the upper mounting hole in the frame, and install the outer insulator, washer, and a new stud retaining nut. Align the lower shock eye in the bracket and install the bolt and nut. Extend the shock, insert the lower shock stud through the hole in the bracket, and install a new self-locking retaining nut. Attach the airline, remove the jack stands, and lower the vehicle.

The steering knuckle should be inserted into the lower mounting flange of the strut assembly, and the two bolts should be installed. If recommended, new bolts and nuts should be used and tightened to the specified torque.

A new hydraulic shock absorber should be installed after bleeding the air from it.

Park the vehicle on level ground, turn off the engine, and set the parking brake. Push down at each corner of the vehicle and observe if it stops moving and returns to a level position within one or two bounces.
