Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to avoid electrical issues.

2. Lift the Vehicle

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

3. Remove the Wheel

Use a lug wrench to loosen and remove the lug nuts.
Take off the wheel and set it aside.

4. Remove the Brake Caliper and Rotor

Use a socket set to remove the caliper mounting bolts.
Carefully hang the caliper using a bungee cord or similar device to avoid stress on the brake line.
Remove the brake rotor by unscrewing any retaining screws if necessary.

5. Replace the Wheel Bearing

Remove the wheel bearing hub assembly using a socket set.
If applicable, use a bearing puller to extract the old bearing from the hub.
Clean the hub area where the new bearing will be installed.
Press the new wheel bearing into the hub using a bearing press or appropriate tools. Ensure it is properly seated.

6. Reassemble Components

Reinstall the brake rotor and caliper, tightening bolts to manufacturer specifications (typically 70-90 ft-lbs for caliper bolts).
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and use a torque wrench to tighten the lug nuts to the manufacturer's specifications (usually 100-120 ft-lbs).

7. Final Checks

Reconnect the negative battery terminal.
Test the vehicle for proper operation and to ensure the noise is eliminated.
