Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, wheel bearing puller.
Safety Warnings: Disconnect the battery before working on electrical systems, and ensure the vehicle is secure on jack stands.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle with a jack and support it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Remove Brake Caliper and Rotor

Unbolt the brake caliper from its bracket using a socket set.
Carefully hang the caliper using a bungee cord or wire, ensuring not to stress the brake line.
Remove the rotor by pulling it straight off the hub.

4. Remove Wheel Bearing

Use a wheel bearing puller to extract the old bearing from the hub assembly.
Clean the hub surface with a wire brush to remove any debris or rust.

5. Install New Wheel Bearing

Apply a thin layer of grease to the new bearing's outer surface.
Press or tap the new bearing into place, ensuring it is seated evenly.
Reassemble the rotor, brake caliper, and wheel in reverse order of removal, ensuring all bolts are tightened to the manufacturer's torque specifications.
