Solution

1. Preparation

Gather tools: OBD-II scanner, jack and jack stands, tire pressure gauge, socket set, torque wrench.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Tire Inspection and Replacement (if necessary)

Visual Inspection: Check for uneven wear patterns, bulges, or punctures on all tires.
Tire Pressure Check: Use a tire pressure gauge to ensure all tires are inflated to manufacturer specifications.
Replacement:
- If tires are worn or damaged, remove each tire using a socket set.
- Install new tires, ensuring they are mounted correctly and torqued to the manufacturer's specifications (usually around 80-100 lb-ft).

3. Wheel Bearing Inspection and Replacement (if necessary)

Lift the Vehicle: Use a jack to elevate the vehicle and secure with jack stands.
Check for Play: Spin each wheel and listen for unusual noises; wobble indicates bearing wear.
Remove Wheel Hub Assembly: If bearings are faulty, remove the wheel hub using a socket set.
Replace Bearings: Install new bearings, ensuring they are greased properly and seated correctly in the hub.

4. Drivetrain Inspection and Repair (if necessary)

Visual Inspection of Driveshaft: Look for any signs of wear, rust, or damage on the driveshaft.
Check Differential Fluid: Ensure the fluid is at the correct level and is clean; replace if dark or contaminated.
Repair or Replace Components: If damage is found, replace the driveshaft or repair the differential as necessary.

5. Final Checks

Reattach all components securely and lower the vehicle.
Test drive the vehicle to confirm the noise has been resolved.
