Solution

1. Preparation

Gather tools and parts required for inspection and repair.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Tire Inspection

Sub-steps:
1. Remove hubcaps or wheel covers if necessary.
2. Inspect each tire for uneven wear patterns, bulges, or foreign objects.
3. Check tire pressure using a pressure gauge and inflate to the manufacturer's recommended PSI if low.
Tools Required: Tire pressure gauge, jack, jack stands.

3. Wheel Bearing Replacement (if necessary)

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to gain access to the hub assembly.
3. Disconnect the brake caliper and rotor to expose the wheel bearing.
4. Remove the bearing using a bearing puller or appropriate tool.
5. Install the new bearing, ensuring it is properly seated.
6. Reassemble the brake components and wheel.
Tools Required: Jack, jack stands, socket set, bearing puller, torque wrench.

4. Drivetrain Inspection (if necessary)

Sub-steps:
1. Inspect the differential fluid level and condition; top off or replace if needed.
2. Check for any signs of leakage around the axles and differential seals.
3. Inspect CV joints for cracks or damage; replace if necessary.
Tools Required: Socket set, fluid pump, differential fluid, CV joint replacement parts.
