Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, wheel bearing puller, and grease.
Safety Warnings: Ensure the vehicle is on a flat surface, engage the parking brake, and use jack stands for safety.

2. Remove Wheel

Loosen lug nuts with a lug wrench.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Access Wheel Bearing

Remove the brake caliper by unbolting it from the bracket (use a socket set).
Secure the caliper using a wire to prevent strain on the brake line.
Remove the brake rotor by sliding it off the hub.

4. Remove Old Wheel Bearing

Remove the wheel hub nut using the appropriate socket.
Use a wheel bearing puller to extract the old wheel bearing from the hub.
Inspect the hub for any damage or scoring before installing the new bearing.

5. Install New Wheel Bearing

Lubricate the new wheel bearing with high-temperature grease.
Press the new wheel bearing into the hub using a bearing press or the wheel bearing puller in reverse.
Reinstall the wheel hub nut and torque it to the manufacturer's specifications.

6. Reassemble Components

Place the brake rotor back onto the hub.
Reattach the brake caliper securely.
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower Vehicle and Finalize

Carefully lower the vehicle off the jack stands.
Torque the lug nuts to the manufacturer's specifications in a star pattern.
Test the wheel bearing by turning the wheel and listening for any abnormal sounds.
