Removal & Installation
- Raise and support the vehicle safely. Support the vehicle so the control arms hang free.
- Remove rear wheel and tire assemblies.
- If equipped with ELC, disconnect the ELC height sensor on the right control arm and/or the parking brake cable retaining clip on the left control arm.
- Unfasten the rear stabilizer shaft from the bracket on the knuckle.
- Place a proper coil spring removal tool securely on a transmission jack and position it to cradle the control arm bushings.
- Place a chain around the spring and through the control arm as a safety measure, then raise the jack to remove the tension from the control arm pivot bolts.
- Remove the pivot bolt and nut from the rear of the control arm.
- Slowly, maneuver the jack to relieve tension from the front control arm pivot bolt.
- Lower the jack to allow the control arm to pivot downward.
Do not apply force to the control arm and/or ball joint to remove the spring. Proper maneuvering of the spring will allow for easy removal.
- When all the compression is removed from the spring, remove the safety chain, spring and the insulators.
- Inspect the insulators carefully and replace them if they are cut or worn. If the vehicle has over 50,000 miles (80,450 km).
- Snap the upper insulator on the spring prior to installation.
- Position the lower insulator and spring in the vehicle. Install the coil springs so the upper end of the springs are positioned properly, as shown in the accompanying figure.
- Raise the control arm into position, using the coil spring tool mounted on a transmission jack.
- Slowly maneuver the jack to allow the installation of the front and rear control arm pivot bolts and nuts.
- Attach the rear stabilizer shaft to the knuckle bracket.
- If equipped, connect the ELC height sensor link on the right control arm and/or the parking brake cable retaining clip on the left control arm.
- Install the tire and wheel assemblies.
- Remove the jack from under the vehicle, then carefully lower the vehicle.
The control arm retainers must be tightened with the vehicle unsupported and resting on its wheels at the normal trim height. Failure to do this can adversely affect ride and handling.
- Tighten the control arm pivot nuts to 85 ft. lbs. (115 Nm).
Tighten the control arm pivot bolts to the following specifications:
- 1986-90 vehicles: 125 ft. lbs. (170 Nm)
- 1991-93 vehicles: 138 ft. lbs. (187 Nm)
- 1994 vehicles: 118 ft. lbs. (160 Nm)
- 1995-99 vehicles: 134 ft. lbs. (182 Nm)
- Tighten the stabilizer support bolt to 13-14 ft. lbs. (17-18 Nm).
