Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Torque wrench
- Mechanic's stethoscope
- Wheel chocks
Ensure the vehicle is on a level surface and engage the parking brake.

2. Remove Wheel

Loosen the lug nuts using a socket wrench while the vehicle is on the ground.
Use a jack to lift the vehicle and securely place it on jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Wheel Bearing

Inspect: Check the wheel hub for any signs of damage or wear.
If replacement is needed:
- Remove the brake caliper and rotor by unscrewing the caliper bolts and sliding the caliper off.
- Remove the wheel hub assembly by unscrewing the hub bolts and disconnecting any electrical connectors if applicable.
- Note: Use a torque wrench to ensure proper reassembly torque specifications are followed.
Replace: Install the new wheel bearing assembly into the hub. Ensure it’s seated correctly and secure it with the hub bolts.

4. Reassemble Components

Reinstall the brake rotor and caliper, ensuring all bolts are tightened to manufacturer specifications.
Place the wheel back on and hand-tighten the lug nuts.

5. Lower Vehicle and Final Checks

Lower the vehicle back to the ground and torque the lug nuts to the manufacturer’s specifications.
Perform a test drive to confirm the noise has been resolved.
