Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely supported with jack stands.
Disconnect the negative battery terminal to avoid any electrical issues.

2. Remove Rear Wheel

Use a jack to lift the rear of the vehicle.
Remove lug nuts using a socket set and take off the rear wheel.

3. Inspect and Replace Components

Inspect Shocks/Struts:
- Check for oil leaks or physical damage.
- If damaged, replace with new shocks or struts. Use a torque wrench to tighten the mounting bolts to the manufacturer’s specifications.
Inspect Bushings:
- Check for cracks or deterioration in the rubber bushings.
- If worn, remove the old bushings using a bushing removal tool and install new ones. Ensure they are seated properly.
Inspect Control Arms and Links:
- Inspect for bending or damage.
- Replace if necessary by removing the bolts with a socket set, and install the new components.

4. Reassemble

Reattach the rear wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and torque the lug nuts to the manufacturer’s specifications.

5. Final Checks

Reconnect the negative battery terminal.
Test the vehicle by driving on uneven surfaces to ensure the noise is resolved.
