Remove the muffler support bracket from the rear frame rail.

To remove the front suspension lower control arm, begin by loosening the wheel lug nuts, raising the front of the vehicle, and supporting it with jackstands. Remove the wheel, then take off the brake caliper and support it with wire to prevent strain on the brake hose. Remove the brake disc from the front hub/bearing assembly. If the vehicle has 15-inch wheels, remove the ball joint heat shield from the steering knuckle by taking out the two bolts. Loosen the lower ball joint castle nut and use a hammer to strike the boss on the steering knuckle until it separates from the lower ball joint stud. Be careful not to damage the lower control arm, ball joint grease seal, or inner CV joint during this process. Once the ball joint stud is released, remove the castle nut. Next, remove the shock absorber clevis-to-lower control arm bolt and detach the clevis from the lower control arm. Then, disconnect the stabilizer bar link from the lower control arm and remove the bolts attaching the stabilizer bar bushing clamp to the front suspension cross member and the vehicle body. Lower one side of the stabilizer bar away from the lower control arm. Remove the nut and bolt attaching the lower control arm to the front suspension cross member, and then separate the front and rear of the lower control arm from the front suspension cross member, being cautious not to damage the ball joint seal against the steering knuckle during this step. Check the bushings in the lower control arm for signs of deterioration and replace them if necessary at an automotive machine shop.For installation, start by placing the rear and then the front of the lower control arm into the front suspension cradle without tightening the bolts at this time. Connect the lower ball joint to the steering knuckle and tighten the castle nut to the specified torque, then install a new cotter pin. Reverse the removal steps for the remaining components, ensuring to install the ball joint heat shield to prevent boot failure due to excessive heat from the brake disc. After installing the clevis on the lower control arm, use a floor jack under the lower ball joint to raise the lower control arm to simulate normal ride height. Tighten the lower control arm-to-cross member bolts and the shock absorber clevis-to-lower control arm bolt/nut to the specified values. Install the brake disc and caliper, tightening the caliper mounting bolts to the specified torque. Finally, install the wheel and lug nuts, lower the vehicle, and tighten the lug nuts to the specified torque.

Start by installing the upper control arm on the mounting bracket with the bolt heads facing inward. Then, install the coil spring on the shock absorber and the upper shock mount/upper control arm assembly. Install the shock absorber as well. Next, use a floor jack to raise the lower control arm to simulate normal ride height and tighten the shock absorber clevis-to-lower control arm bolt. Finally, install the wheel and lug nuts, lower the vehicle, and tighten the lug nuts.
