Begin by raising and securely supporting the vehicle and removing the wheel and tire assembly. On Eldorado and Seville with a 4.6L engine, remove the road sensing suspension position sensor from the lower control arm. Remove the cotter pin and nut from the ball joint stud and use the appropriate ball joint separator tool to separate the ball joint from the steering knuckle. On Deville and Fleetwood, loosen the stabilizer bar link nut and drill out the three rivets retaining the ball joint to the lower control arm. The recommended drill bit size is Y inch (13 mm).

For 4WD models, the procedure is similar to 2WD models, but a pickle fork-type separator is often needed. To replace the lower balljoint on 4WD models, raise and support the vehicle, remove the wheel and splash shield, disconnect the tie-rod, remove the driveaxle, drill and remove rivets, use a puller to separate the balljoint from the knuckle, then install the new balljoint to the control arm and reassemble. Load the torsion bar, install the driveaxle, connect the tie-rod, reinstall the splash shield and wheel, and lower the vehicle. Finally, tighten the lug nuts to the proper torque specifications.

Raise the vehicle, remove the wheel, caliper, ABS wheel speed sensor, and wiring from the upper control arm. Remove the cotter pin and back off the nut, then use a special tool or balljoint separator to separate the balljoint from the steering knuckle. Drill out the rivets, clean the control arm, and install the new balljoint using nuts and bolts from the kit.

To check lower balljoints on 4WD models, use a dial indicator and prybar to measure deflection.
