Mercury F7AZ-3084-AA Front Suspension Arm Assembly

Remove the wheel lug nuts, raise the vehicle, and remove the wheel. Remove the nut, washer, and bushing from the shock absorber. Use a floor jack under the lower control arm and loosen the stud in the steering knuckle with a hammer. If needed, use a balljoint stud separator. Remove the nut from the upper balljoint stud and the upper control arm pivot shaft bolts. Remove the upper control arm assembly. Inspect the control arm bushings for damage. If damaged, replace at an automotive shop. Reinstall the upper control arm pivot shaft and the two attaching bolts. Insert the upper balljoint stud into the steering knuckle and install the nut or pinch bolt. On pre-1992 models, align the cotter pin hole with the nut slots and install a new cotter pin. Reinstall the wheel and tighten the lug nuts. Lower the vehicle and have the alignment adjusted at a shop.

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 balljoint stud. Loosen the castle nut on the stud. Use sharp raps on the steering knuckle near the stud to release pressure and loosen the stud. Remove the balljoint stud nut. Lower the control arm by removing its mounting bolts.

Install the wheel. Tighten the lug nuts. Remove the jackstands. Lower the vehicle. Visit an alignment shop for caster, camber, and toe-in adjustments as needed.
