To remove the front coil spring, raise the vehicle and remove the wheel, shock absorber, stabilizer bar, and coil spring. The lower control arm is disconnected from the steering knuckle by removing the ball joint stud nut and cotter pin. For installation, the control arm is raised, the spring is guided into position, and the control arm pivot bolts and nuts are installed.

Position the upper control arm pivot shaft on the frame. Install the attaching bolts and washers. Insert the upper balljoint stud into the steering knuckle and secure it with the nut or pinch bolt.

To remove the upper balljoint stud on 1991 and earlier models, you need to remove the cotter pin and then the nut from the upper balljoint stud.

Secure the lower control arm with mounting bolts (not fully tightened initially). Use a spring compressor for 2002 and earlier models and properly seat the spring. Insert the balljoint stud into the steering knuckle. Tighten the castle nut and install a new cotter pin. On 2003 and later models, install the shock absorber/coil spring assembly. For 1988 through 1991 models, attach the stabilizer bar.

Remove the cotter pin from the upper balljoint stud and loosen the stud nut slightly. Place a floor jack under the lower control arm and raise it slightly. Tap the steering knuckle near the upper balljoint stud with a hammer to loosen it. Use a balljoint stud separator if needed (note that this may damage the balljoint boot). Remove the nut from the upper balljoint stud and the upper control arm pivot shaft attaching bolts. Remove the upper control arm and pivot shaft as an assembly.

Begin by loosening the wheel lug nuts. Raise the front of the vehicle and securely support it with jackstands. Remove the front wheel.
