Solution

1. Preparation

Gather tools needed: socket set, jack and jack stands, OBD-II scanner, and a multimeter.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Tire Inspection

Remove the wheel covers (if applicable) and inspect the tires for any foreign objects or uneven tread wear.
Use a tire pressure gauge to check and adjust tire pressures to the manufacturer's specifications.

3. Wheel Bearing Inspection

Safely lift the vehicle using a jack and secure it with jack stands.
Grasp the wheel at the 12 and 6 o'clock positions and wiggle it to check for excessive play.
If play is detected, the wheel bearings may need replacement.

4. Brake Inspection

Remove the wheel to access the brake assembly.
Inspect brake pads for thickness; replace if they are below minimum specifications.
Check rotors for warping or damage; replace if necessary.

5. Electric Motor Inspection

Open the front trunk and inspect the electric motor compartment for any loose connections or signs of wear.
Tighten any loose connections and check for signs of corrosion.
If the issue persists, consult Tesla service for further diagnosis.
