Solution

1. Preparation

Gather tools and parts necessary for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Lift the Vehicle

Use a hydraulic jack to lift the rear of the vehicle.
Secure with jack stands to ensure stability during repairs.

3. Inspect and Replace Suspension Components

Inspect Shock Absorbers and Struts:
- Remove the wheel to access the rear suspension.
- Check for leakage or damage on shock absorbers.
- If defective, remove the top and bottom mounting bolts and replace with new units.
Check Control Arm Bushings:
- Visually inspect the control arm bushings for cracks or deterioration.
- If worn, remove the control arm by unbolting it from the chassis and the rear axle.
- Replace the bushings using a bushing press or a suitable tool.
Check Sway Bar Links:
- Inspect sway bar links for looseness or wear.
- Remove and replace if necessary with new sway bar links.

4. Reassemble and Torque Components

Reattach any removed components, ensuring all bolts are torqued to manufacturer specifications (refer to the Tesla service manual for specific torque values).
Reinstall the wheel and lower the vehicle from jack stands.

5. Finalize and Test Drive

Reconnect the battery terminal.
Conduct a test drive to ensure the clunking noise has been resolved.
