Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Gather tools and safety equipment (gloves, goggles).

2. Tire Inspection

Remove the wheel covers or hubcaps if present.
Inspect tires for uneven wear, bulges, or foreign objects.
Replace any damaged tires and ensure they are properly inflated.

3. Wheel Bearing Inspection

Lift the vehicle using a jack and secure it on jack stands.
Spin each wheel; check for noise or roughness.
If noise is present, remove the wheel and replace the wheel bearing as follows:
- Remove the brake caliper and rotor.
- Disconnect any ABS sensors if applicable.
- Remove the wheel bearing assembly.
- Press in the new bearing and reassemble components.

4. Belt Inspection

Inspect serpentine and accessory belts for wear, cracks, or looseness.
Replace any worn belts using the following steps:
- Loosen the tensioner using a suitable socket.
- Remove the old belt and install the new one, ensuring correct routing.
- Tighten the tensioner to spec.

5. Transmission Fluid Check

Locate the transmission dipstick (if applicable).
Check the fluid level and condition; it should be a bright red color.
If low, add manufacturer-recommended transmission fluid.
If dirty or burnt, consider a transmission fluid change.

6. Test Drive

Reassemble any components removed during inspection.
Lower the vehicle and perform a test drive to confirm the noise has been resolved.
