Remove the shock absorber. Disconnect the center link from the Pitman arm. Use a suitable spring compressor, following the manufacturer's instructions, to relieve tension on the spring. Compress the spring. Remove the nuts and bolts securing the inner end of the lower control arm to the frame. Slowly lower the control arm. Remove the spring and compressor as a unit.

Snap the right parking brake cable into the upper suspension arm retainer. Install the rear stabilizer bar. Connect the height sensor connector link to the upper control arm.

For installation, set the upper insulator on top of the spring, using tape if necessary, place the lower insulator on the lower suspension arm, and install the internal damper in the spring. Place the spring between the suspension arm and the frame, with the pigtail (end of the spring) on the lower suspension arm pointing toward the left side of the vehicle. Raise the lower suspension arm into position, install the pivot bolt and nut, and tighten the nut to the specified torque.

The installation involves placing the spring in the upper seat, reattaching the stabilizer bar link, and tightening pivot bolt nuts to specified torque.
