Solution

1. Preparation

Tools Required: Jack, jack stands, wheel chocks, socket set, torque wrench, OBD-II scanner.
Ensure the vehicle is on a flat surface, turn off the ignition, and engage the parking brake. Disconnect the battery if working on electrical components.

2. Inspect and Clear Debris

Remove any debris found in the wheel wells that may be causing interference. Use a flashlight to inspect hard-to-see areas.
Reassemble any components that were removed to access the wheel wells.

3. Check Power Steering Fluid

If applicable, locate the power steering reservoir and check the fluid level.
If low, top off with the recommended power steering fluid according to Tesla specifications.
Inspect the reservoir and hoses for any signs of leaks.

4. Inspect CV Joints and Axles

Remove the front wheels using a socket set.
Inspect the CV joints for any cracks or tears in the boots. Replace any damaged components.
If noise persists, consider replacing the affected axle.

5. Test Steering Components

With the vehicle still lifted, manually turn the steering wheel while listening for any abnormal noises.
Inspect the tie rods and ball joints for excessive play or wear. Replace any worn components.

6. Reassemble and Lower Vehicle

Re-install the front wheels, ensuring they are torqued to the manufacturer's specifications (typically around 100-120 ft-lbs for Tesla).
Lower the vehicle back to the ground and reconnect the battery if it was disconnected.
