Solution

1. Preparation

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

2. Inspect Suspension Components

Tools Required: Socket set, torque wrench, pry bar
Remove the wheel on the side where the noise is more pronounced.
Inspect the control arms and bushings for wear or damage.
- If damaged, proceed to replace the affected components.

3. Tighten Loose Hardware

Check all bolts and screws associated with the suspension system.
Use a torque wrench to tighten bolts to manufacturer specifications.
Refer to the Tesla service manual for specific torque values.

4. Replace Worn Components

If any bushings, struts, or control arms are found to be worn:
- Remove the old component using the socket set.
- Install the new component and ensure all bolts are torqued to specification.

5. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Reconnect the 12V battery.
Test drive the vehicle over bumps to ensure the clunking noise is eliminated.
