Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety glasses and gloves.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Remove the rear or front tires, depending on the suspected area of noise.

3. Inspect Suspension Components

Shocks/Struts:
- Check for oil leaks around the shock absorbers or struts.
- If damaged, remove the strut assembly using a socket set, paying attention to the torque specifications.
- Replace with new units if necessary, ensuring to torque all bolts to the manufacturer's specifications.
Control Arms and Bushings:
- Inspect control arms and bushings for wear.
- Replace any damaged bushings by pressing them out and pressing in new ones using a bushing tool.
Sway Bar Links:
- Check sway bar links for looseness. Replace if necessary, removing the bolts with a socket set.

4. Reassemble Components

Reinstall the tires and lower the vehicle.
Ensure all bolts are properly torqued to specifications.
Reconnect any exhaust components or heat shields that may have been loosened during the inspection.
