Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, wheel chocks, and a dial indicator (for precise measurement).
Safety Warnings: Ensure the vehicle is on a flat surface and use wheel chocks to prevent rolling. Always wear safety glasses and gloves.

2. Lift the Vehicle

a. Use the jack to lift the vehicle at the recommended lift points.
b. Secure the vehicle with jack stands.

3. Remove the Wheel

a. Loosen the lug nuts using the lug wrench.
b. Remove the lug nuts and take off the wheel.

4. Inspect the Wheel Bearing

a. Check the wheel hub for any visible cracks or signs of wear.
b. Use the dial indicator to measure bearing play by placing it on the hub and moving the wheel in and out.

5. Replace if Necessary

a. If the bearing is found to be faulty, remove the brake caliper (if applicable) and the rotor.
b. Use a bearing puller to remove the old bearing from the hub.
c. Clean the hub surface and install the new bearing, ensuring it is seated correctly.
d. Reinstall the rotor and caliper, and torque all fasteners to the manufacturer's specifications.

6. Reassemble the Wheel

a. Place the wheel back onto the hub.
b. Hand-tighten the lug nuts initially, then use the torque wrench to tighten them to the specified torque value (usually around 100-120 ft-lbs for Tesla vehicles).

7. Lower the Vehicle

a. Carefully remove jack stands and lower the vehicle back to the ground.
