REMOVAL & INSTALLATION
See Figure 1
- Raise and support the vehicle safely. Remove the tire and wheel assembly.
- If equipped, disconnect the ELC height sensor on the right control arm and/or the parking brake cable retaining clip on the left control arm.
- Remove the cotter pin, then unfasten the suspension adjustment link retaining nut and separate the link assembly from the control arm. For more information, refer to the procedure located later in this section.
- Remove the spring, as outlined earlier in this section.
- Remove the cotter pin and slotted nut from the ball joint. Turn the nut over and install it with the flat portion facing up. Do NOT tighten the nut.
- Use a suitable tool to separate the ball joint from the steering knuckle.
- Remove the control arm from the vehicle.
Position the control arm ball joint stud in the steering knuckle. Install a new slotted nut and tighten as follows:
- Tighten the nut to 88 inch lbs. (10 Nm).
- Tighten the nut an additional 4 flats; the torque should be 40 ft. lbs. (55 Nm), minimum. It may be necessary to partially load the joint to keep the ball stud from rotating while the nut is being tightened.
- Tighten the nut up to one more flat to align the slot with the cotter pin hole.
- Install a new cotter pin.
- Install the spring, as outlined earlier in this section.
- Connect the adjustment link assembly to the control arm and secure with the retaining nut. Tighten the nut to 63 ft. lbs. (85 Nm).
- If equipped, connect the ELC height sensor on the right control arm and/or the parking brake cable retaining clip on the left control arm.
- Install the tire and wheel assembly.
- Lower the vehicle, then tighten the wheel lug nuts to 100 ft. lbs. (136 Nm).
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:
- 1987-90 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).
