Removal starts by removing the shock absorber upper attaching nut, washer, and bushing to detach the upper end of the shock absorber. For upper balljoint replacement on 1992 and later models, it's crucial to mark the location of the alignment marks on the adjustment cams before removing the two retaining nuts.

Start by raising the rear of the vehicle and securely supporting it on jackstands.

If any free play is noted, check the steering gear mounts and the tie-rod ends for looseness. Verify the steering gear mount bolt tightness. If the tie-rods are loose, the ball joints may be worn.

For 2003 and later models, remove the three shock absorber upper mounting nuts, the brake caliper, and the brake disc. Additionally, remove the upper and lower stabilizer bar links. Remove the upper balljoint nut and separate the control arm from the steering knuckle. Finally, remove the lower mounting bolt and the shock absorber/coil spring assembly from the front end of the vehicle.

Allow the rear axle to hang freely until the shock absorbers finish venting through the compressor. Support the rear axle with a floor jack to prevent it from dropping when the shock absorbers are disconnected.

If the vehicle continues to move up and down or fails to return to its original position, a worn or weak shock absorber is likely the reason.
