Place the spring upper insulator on the spring and secure it with tape. Install the spring compressor according to the manufacturer's instructions and compress the spring. Position the spring on the lower control arm, ensuring the lower end properly engages with the seat. On 1988 through 1991 models, align the end of the spring to cover the first hole in the lower control arm spring seat, leaving the second hole uncovered. Carefully raise the lower control arm, guiding the inner end to align with the bolt holes in the frame. Install the pivot bolts into the control arm and the frame. Loosely attach the nuts on the bolts. Attach the center link to the Pitman arm. Attach the lower end of the shock absorber to the lower control arm. On 1988 through 1991 models, attach the stabilizer bar to the link. Install the shock absorber. Install the wheels. Remove the jackstands, lower the floor jack, and lower the vehicle. Tighten the wheel lug nuts to the specified torque. After lowering the vehicle, tighten the lower control arm pivot bolt nuts to the specified torque. This can also be done with the vehicle on jackstands by raising the lower control arm with a floor jack to simulate normal ride height.

Raise the axle assembly with the floor jack and insert the studs on the lower ends of the shocks into their holes in the brackets on the axle tubes. Install the stud retaining nuts, but don't fully tighten them yet.

This procedure specifically applies to 2002 and earlier models. Coil spring removal and installation on 2003 and later models are combined with shock absorber replacement.

Loosen the wheel lug nuts.
