Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety when working on electrical components.

2. Remove Wheel and Brake Components

Use a lug wrench to loosen the lug nuts while the vehicle is on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.
Remove the brake caliper by unbolting it and hanging it using a bungee cord (do not let it dangle by the brake line).
Remove the brake rotor if necessary.

3. Remove the Wheel Hub Assembly

Remove any dust caps or retaining clips on the hub assembly.
Unbolt the wheel hub assembly from the steering knuckle using a socket set (note the torque specifications for reinstallation).
Disconnect any ABS sensor wiring if applicable.
Carefully remove the hub assembly from the vehicle.

4. Install New Wheel Bearing

Press the new wheel bearing into the hub assembly using a bearing press (if applicable) or replace the entire hub assembly if it is one unit.
Ensure the bearing is seated properly and sealed.

5. Reassemble Components

Reinstall the wheel hub assembly onto the steering knuckle.
Reconnect the ABS sensor wiring.
Reinstall the brake rotor and caliper.
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications.

6. Final Checks

Reconnect the battery.
Test drive the vehicle to ensure the noise has been resolved and everything is functioning correctly.
