- Carefully remove the link and inspect it for wear.
Struts or Shocks:
- Remove the wheel to access the strut/shock assembly.
- Use a socket set to remove the top and bottom bolts securing the strut or shock.
- Carefully detach the strut or shock from the vehicle.

3. Inspect and Replace Components

Inspect:
- Check the strut mounts, bushings, and any other attaching points for wear and tear.
Replace:
- If any components are found to be worn, replace them with new parts.
- Reinstall the new struts or shocks and torque to manufacturer specifications.
- Reattach sway bar links securely.

4. Reassemble and Test

Reinstall the wheels and lower the vehicle to the ground.
Reconnect the battery.
Perform a test drive, ensuring the clunking noise is resolved.
