Solution

1. Preparation

Tools Required: Jack, jack stands, tire pressure gauge, torque wrench, mechanic's stethoscope.
Ensure the vehicle is on a flat surface and the engine is turned off.
Disconnect the battery if working on electrical components.

2. Tire Inspection

Remove the hubcaps (if applicable) and inspect each tire for uneven wear or damage.
Use a tire pressure gauge to check and adjust tire pressures to the specifications found in the owner's manual.
If tires are worn unevenly, consider replacing them.

3. Wheel Bearing Inspection

Lift the vehicle with a jack and secure with jack stands.
Grasp each wheel at the 12 and 6 o'clock positions and try to rock it back and forth. If there is movement, the bearing may need replacement.
Use a mechanic's stethoscope to listen for grinding or roughness while spinning the wheel.

4. Drivetrain Inspection

Inspect the driveshaft and differential for any signs of leakage or damage.
Check the CV joints for any signs of wear or damage.
If any components are found to be faulty, proceed with replacement.

5. Reassembly and Testing

Reinstall any components removed during inspection.
Tighten all fasteners to the manufacturer's torque specifications.
Reconnect the battery and lower the vehicle.
