Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat, level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on where the noise is originating.
Secure the vehicle with jack stands for safety.

3. Inspect Suspension Components

Shocks/Struts:
- Check for oil leakage, dents, or physical damage.
- If damaged, remove the old strut/shock using a socket set and replace with a new one.
Bushings:
- Examine control arm bushings for signs of cracking or wear. Replace any worn bushings.
- To replace, remove the control arm if necessary, and press in new bushings.
Sway Bar Links:
- Inspect sway bar links for play or damage. Replace if necessary, using a socket set to remove and install new links.

4. Reassemble and Lower the Vehicle

Ensure all components are securely fastened to the manufacturer’s torque specifications.
Remove jack stands and lower the vehicle back to the ground.

5. Test Drive

Conduct a test drive over bumps to ensure the clunking noise has been resolved.
