Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the 12V battery to ensure electrical safety.

2. Inspect and Replace Suspension Components

Inspect Control Arms and Bushings:
- Remove the wheel using a socket set.
- Check control arms for cracks or excessive wear; replace if necessary.
- Inspect bushings for tears; replace with OEM parts if damaged.
Check Struts and Shocks:
- Use a jack to lift the vehicle and secure it with jack stands.
- Inspect struts for leaks or damage; replace if oil is present.
- Confirm the strut mounts are secure and replace if worn.
Inspect Sway Bar Links:
- Locate the sway bar links and check for play.
- Tighten or replace links if they are loose or damaged.

3. Reassemble and Test

Reinstall the wheel and tighten lug nuts to the manufacturer’s specified torque value (typically 100-120 ft-lbs).
Reconnect the battery and lower the vehicle.
Perform a test drive to confirm that the clunking noise has been resolved.
