Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Allow the vehicle to cool down if it has been driven recently.

2. Inspect Tires

Tools Required: Tire pressure gauge, socket set.
Check tire pressure and ensure it matches the manufacturer's specifications.
Inspect tires for visible damage, bulges, or uneven tread wear.
Rotate tires if necessary to balance wear.

3. Check Wheel Bearings

Tools Required: Jack, jack stands, torque wrench.
Lift the vehicle using a jack and secure it with jack stands.
Grasp the wheel at the 12 o'clock and 6 o'clock positions and shake it to check for play.
If play is present, replace the wheel bearing.

4. Inspect Brake Components

Tools Required: Brake cleaner, socket set, torque wrench.
Remove the wheel and inspect brake pads, rotors, and calipers.
Clean any debris from the brake components using brake cleaner.
Replace worn brake pads or damaged rotors as necessary.

5. Test Drive

Reassemble any components or wheels removed for inspection.
Lower the vehicle back to the ground and remove the jack stands.
Conduct a test drive to ensure the noise has been resolved.
