- Replace with new shock absorbers/struts if damaged.
Bushings and Mounts:
- Inspect control arm bushings and sway bar bushings.
- Remove any worn or damaged bushings and replace with new ones.
Sway Bar Links:
- Inspect sway bar links for wear.
- If damaged, remove the old sway bar link and install a new one.

4. Reassemble and Lower the Vehicle

Reattach the wheel and torque the lug nuts to the manufacturer’s specifications.
Lower the vehicle from the jack stands and remove the jack.

5. Final Inspection

Conduct a final visual inspection to ensure all components are securely fastened.
