Grasp each front tire at the front and rear edges, push in at the front, pull out at the rear, and feel for play in the steering system components.

Compress the shock absorber to clear the hole in the frame, and then remove the inner insulator and washer from the upper retaining stud. Some models may have shocks with a plastic dust tube, which can be loosened using a wrench. Remove the lower retaining nut and the lower shock absorber mounting stud from the mounting bracket to complete the removal process.

Note the order of installation for any bushings and grommets above and below the upper control arm. Inspect these parts for cracks, tears, and deterioration, replacing them as necessary.

Locate the upper retaining nut on top of the frame, and if necessary, hold the piston rod with a wrench or locking pliers while loosening the nut. Remove the upper nut, washer, and insulator from the stud on the upper side of the frame.

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.

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.
