Locate the sway bar links and inspect for any play.
Remove the nuts securing the sway bar link to the sway bar and control arm.
Replace with a new sway bar link, ensuring proper orientation.
Torque the nuts to the specified value.

C. Control Arm Bushings

Identify the control arms and inspect the bushings for wear.
If replacement is needed, unbolt the control arm from the vehicle.
Press out the old bushings and press in new ones.
Reinstall the control arm and torque bolts to the manufacturer’s specifications.

4. Reassemble the Vehicle

Reinstall the wheel and torque lug nuts to the specified value.
Lower the vehicle from the jack stands using the floor jack.

5. Final Inspection

Conduct a visual inspection to ensure all components are secure and properly installed.
Test drive the vehicle to confirm the clunking noise has been resolved.
