Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Lift the vehicle using a jack and support it with jack stands.

2. Remove Wheel

Use a socket set to loosen the lug nuts, then remove the wheel.
Tools Required: Socket set, lug wrench.

3. Access Wheel Bearing

Remove the brake caliper by unbolting it from the bracket; support it with a wire to prevent strain on the brake line.
Remove the brake rotor by pulling it straight off the hub.
Tools Required: Socket set, caliper hanger.

4. Remove Wheel Bearing Assembly

Remove any retaining clips or bolts securing the hub assembly.
Disconnect the ABS sensor wire if present.
Using a bearing puller, carefully extract the wheel bearing from the hub.
Tools Required: Bearing puller, socket set.

5. Install New Wheel Bearing

Clean the hub area thoroughly before installation.
Apply a suitable amount of grease to the new wheel bearing.
Install the new wheel bearing in reverse order of removal, ensuring it is seated properly.
Torque specifications for hub bolts should be adhered to (refer to manufacturer's specifications).

6. Reassemble Components

Reattach the brake rotor and caliper, ensuring all bolts are torqued to specification.
Reinstall the wheel and tighten the lug nuts in a star pattern to the appropriate torque setting.
Tools Required: Torque wrench.

7. Lower Vehicle and Test

Remove jack stands and lower the vehicle.
Conduct a test drive to ensure the noise has been resolved.
