Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, torque wrench, wheel chocks, safety glasses, gloves.
Safety Warning: Ensure the vehicle is on a flat surface and securely supported by jack stands before performing any work.

2. Remove Wheel

Loosen the lug nuts on the affected wheel while the vehicle is still on the ground.
Jack up the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove Brake Components

Detach the brake caliper by removing the caliper mounting bolts using a socket wrench.
Hang the caliper using a bungee cord or wire to avoid straining the brake line.
Remove the brake rotor by taking out the retaining screws if applicable.

4. Inspect and Replace Wheel Bearing

Remove the wheel hub assembly by unbolting it from the steering knuckle.
Use a bearing puller to extract the old wheel bearing from the hub.
Clean the hub assembly and inspect for any damage.
Install the new wheel bearing into the hub using a press or appropriate tool.
Reassemble the wheel hub and mount it back onto the steering knuckle.

5. Reinstall Brake Components and Wheel

Reinstall the brake rotor and secure it with screws.
Reattach the brake caliper and tighten the mounting bolts to the manufacturer's torque specifications.
Place the wheel back on and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications.
