Shock Absorbers/Struts:
- Check for oil leaks and physical damage.
- If necessary, replace the shock absorbers/struts using a socket set to remove bolts.
Control Arms and Bushings:
- Inspect for wear and tear on bushings.
- Replace any damaged bushings by removing the control arm if needed.
Sway Bar Links:
- Check for loose or damaged sway bar links.
- Tighten or replace sway bar links as necessary.

4. Tighten Loose Fasteners

Go through each suspension component and use a torque wrench to tighten any loose bolts to manufacturer specifications.
Refer to the service manual for specific torque values for suspension components.

5. Reassemble and Lower Vehicle

Ensure all tools and debris are removed from under the vehicle.
Carefully lower the vehicle from the jack stands and remove the jack.
