Solution

1. Preparation

Tools Needed:
- Jack and jack stands
- Torque wrench
- Socket set
- Wheel chocks
- Clean rags
- Bearing grease (if replacement is needed)
Safety Warning: Ensure the vehicle is on a flat surface and engage the parking brake before lifting. Always use jack stands for safety.

2. Remove Wheel

Loosen Lug Nuts: Slightly loosen the lug nuts on the wheel you are inspecting while the vehicle is still on the ground.
Lift the Vehicle: Use the jack to raise the vehicle and secure it on jack stands.
Remove Lug Nuts: Fully remove the lug nuts and take off the wheel.

3. Inspect Wheel Bearings

Visual Inspection: Look for any signs of damage or corrosion on the bearing housing and surrounding components.
Check Wheel Play: With the wheel off, check for any lateral movement by rocking the hub assembly.
Spin Test: Rotate the hub by hand to check for smoothness and any abnormal noises.

4. Repack or Replace Bearings (if necessary)

Remove Dust Cap: If the bearings need to be serviced, remove the dust cap using a flathead screwdriver.
Take Out Bearings: Carefully remove the bearings and inspect them for wear. Clean thoroughly with a degreaser and inspect for pitting or wear.
Repack with Grease: If bearings are in good condition, repack them with high-quality bearing grease.
Reinstall Bearings: Place the bearings back into their housing and ensure they’re seated correctly.
Reinstall Dust Cap: Secure the dust cap back in place.

5. Reinstall Wheel

Place Wheel Back: Position the wheel back onto the hub.
Tighten Lug Nuts: Hand-tighten the lug nuts before lowering the vehicle.
Lower Vehicle: Carefully remove the jack stands and lower the vehicle to the ground.
Torque Lug Nuts: Use a torque wrench to tighten the lug nuts to the manufacturer's specifications (typically 100-110 ft-lbs for Tesla).
