Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and set the parking brake.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Worn Components

Belt and Pulley Inspection:
- Remove the engine cover, if applicable.
- Check the serpentine belt for fraying or cracks.
- Use a multimeter to check the tensioner; replace it if it is not holding proper tension.
- Replace the serpentine belt if damaged.
Brake Component Inspection:
- Remove the wheel using a socket set.
- Inspect brake pads for wear; replace if less than 3mm thick.
- Check rotors for scoring or warping; replace if necessary.

3. Wheel Bearing Service

Wheel Bearing Inspection:
- Lift the vehicle and secure it on jack stands.
- Spin the wheel by hand to listen for noise.
- If noise is present, remove the wheel and brake caliper.
- Inspect the wheel bearing for play; replace if any movement is detected.

4. Reassemble and Test

Reinstall any components that were removed.
Torque the lug nuts to manufacturer specifications (typically 80-100 ft-lbs).
Reconnect the battery and lower the vehicle.
Test drive to confirm that the noise has been resolved.
