- If damaged, remove the old shock by loosening the mounting bolts at the top and bottom.
- Install the new shock absorber and torque the bolts to the manufacturer's specifications.
Check sway bar links and bushings:
- Use a pry bar to check for play in the sway bar links.
- If worn, remove the bolts securing the sway bar link to the sway bar and the lower control arm.
- Replace with new sway bar links and torque to specifications.
Examine control arm bushings and ball joints:
- Inspect for cracks or excessive play.
- If worn, remove the control arm from the vehicle.
- Replace the bushings or ball joints as necessary, ensuring to torque all bolts to specifications upon reinstallation.

3. Reassemble and Lower the Vehicle

Reinstall any components removed during inspection.
Ensure all fasteners are tightened to the specified torque values.
Lower the vehicle and remove the jack stands.
