Ensure the vehicle is stable before proceeding.

3. Inspect and Replace Worn Components

Sway Bar Links:
- Remove the bolt securing the sway bar link to the sway bar using a socket set.
- Replace with a new sway bar link, tightening to the manufacturer’s specified torque.
Shock Absorbers/Struts:
- Remove the upper and lower mounting bolts of the shock absorber or strut.
- Replace with new units, ensuring proper alignment and tightening to specifications.
Bushings:
- Check all bushings for wear; if damaged, remove and replace them.
- Use a bushing removal tool for easier extraction.

4. Reassemble and Lower the Vehicle

Reinstall all components in reverse order of removal.
Ensure all bolts are tightened to the manufacturer’s torque specifications.
Carefully lower the vehicle from the jack stands.

5. Test Drive

Conduct a test drive to confirm that the rattling noise is resolved.
Listen for any abnormal sounds and check the vehicle's handling.
