Solution

1. Preparation

Park the vehicle on a level surface and ensure it is turned off.
Gather required tools and parts.
Tools Required: Jack, jack stands, tire pressure gauge, socket set, torque wrench.

2. Tire Inspection

Remove the wheel covers or hubcaps, if applicable.
Use a tire pressure gauge to check the tire pressure; adjust to manufacturer specifications if needed.
Inspect the tire tread for any signs of uneven wear, bulging, or embedded debris.
Rotate or replace tires if uneven wear is observed.

3. Wheel Bearing and Suspension Check

Lift the vehicle using a jack and secure it with jack stands.
Check wheel bearings by shaking the wheel; listen for any grinding or excessive play.
Inspect suspension components (control arms, bushings, and struts) for any signs of wear or damage.
Replace any worn components as necessary.

4. Electric Motor Inspection

Safely access the electric motor by removing any necessary covers or panels.
Visually inspect the motor and surrounding components for signs of wear, overheating, or damage.
If no visible issues are found, perform a noise test by gently spinning the motor and listening for abnormal sounds.
If the motor is faulty, consult Tesla service for replacement.

5. Reassembly and Final Checks

Reassemble any removed components in reverse order, ensuring all fasteners are tightened to manufacturer torque specifications.
Lower the vehicle and perform a final inspection.
