Solution

1. Preparation

Tools Required: Wheel chocks, jack and jack stands, lug wrench, torque wrench, socket set, bearing puller, grease, new wheel bearing kit.
Safety Warnings: Ensure the vehicle is on a flat surface, engage the parking brake, and wear safety glasses.

2. Remove Wheel

Loosen the lug nuts slightly 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.

3. Remove Brake Components

Remove the brake caliper by unbolting it from the bracket (use a socket set).
Secure the caliper to the suspension with a wire to avoid stress on the brake line.
Take off the brake rotor by removing the retaining screws or bolts.

4. Remove Old Wheel Bearing

Remove the 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 area thoroughly to prepare for installation.

5. Install New Wheel Bearing

Apply a thin layer of grease to the new wheel bearing and press it into the hub assembly.
Reinstall the hub assembly onto the steering knuckle and secure it with the manufacturer-recommended torque specifications.

6. Reassemble Brake Components

Reattach the brake rotor and secure it with screws or bolts.
Reinstall the brake caliper and tighten it to the specified torque.

7. Reattach Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and torque the lug nuts to the manufacturer's specifications.
