Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery if working on electrical components.

2. Tire Inspection and Maintenance

Check Tire Pressure:
- Use a tire pressure gauge to ensure all tires are inflated to the manufacturer's recommended levels.
- Adjust pressure as necessary.
Inspect for Uneven Wear:
- Examine all tires for signs of uneven wear.
- Rotate or replace tires if significant uneven wear is found.

3. Wheel Bearing Inspection

Lift the Vehicle:
- Use a jack and secure with jack stands to safely lift the vehicle.
Check for Play:
- Grasp the wheel at the 12 and 6 o'clock positions and try to rock it back and forth.
- If play is felt, the wheel bearing may need replacement.

4. Drivetrain Component Check

Inspect CV Joints and Axles:
- Look for any visible damage or excessive grease leakage around the CV joints.
- Rotate the wheels while listening for unusual noises from the CV joints.
Replace Faulty Components:
- If any worn or damaged parts are identified, replace them as necessary. Ensure to use OEM or high-quality replacement parts.

5. Reassemble and Test

Lower the vehicle safely.
Reconnect the battery if it was disconnected.
Test drive the vehicle to confirm that the humming noise has been resolved.
