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.

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.

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.

Visually inspect the steering system components for damage and distortion. Look for leaks and damaged seals, boots, and fittings.

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.

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.
