Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Use wheel chocks to secure the vehicle.
Safety equipment: gloves and safety glasses.

2. Raise the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle, depending on which wheel is making the noise.
Secure the vehicle on jack stands for safety.

3. Remove Wheel

Use a socket set to remove the lug nuts on the noisy wheel.
Take off the wheel and set it aside.

4. Inspect and Replace Brake Components

Inspect Brake Pads: Check thickness; replace if less than 3mm.
- Tools Required: Brake pad spreader, torque wrench.
- If replacing, carefully unbolt the caliper and slide it off the rotor.
Inspect Brake Rotors: Check for surface scoring and warping.
- If damaged, replace the rotor.
- Use a brake cleaner to clean the rotor surface before reinstallation.
Check Caliper Function: Ensure it moves freely; lubricate if necessary.

5. Inspect Wheel Bearings

Remove the caliper and rotor to access the wheel bearing.
Check for play by wiggling the hub; replace if loose or rough.
Tools Required: Bearing puller, torque wrench.

6. Reassemble and Test

Reinstall the rotor and caliper, ensuring all bolts are torqued to manufacturer specifications.
Replace the wheel and lug nuts, tightening them in a crisscross pattern.
Lower the vehicle and perform a test drive to confirm the noise is eliminated.
