Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, tire pressure gauge.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery for safety if working on electrical components.

2. Tire Inspection

Sub-steps:
- Check tire pressure using a tire pressure gauge and adjust to the manufacturer's specifications.
- Examine tires for uneven wear, bulges, or foreign objects embedded in the tread.
- Rotate tires to ensure even wear if necessary.

3. Wheel Bearing Inspection

Sub-steps:
- Lift the vehicle using a jack and secure it on jack stands.
- Remove the wheel using a lug wrench.
- Spin the hub and listen for grinding or roughness.
- If noise is present, replace the wheel bearing using the following steps.

4. Wheel Bearing Replacement

Sub-steps:
- Remove the brake caliper and rotor.
- Unbolt the wheel bearing assembly and extract it from the hub.
- Install the new wheel bearing, ensuring proper alignment.
- Reassemble the brake rotor and caliper, torquing to manufacturer specifications.

5. Drivetrain Component Inspection

Sub-steps:
- Inspect CV joints for cracks or torn boots.
- Check the differential fluid level and condition; replace if contaminated.
- If any issues are found, replace the damaged components and refill differential fluid as needed.
