Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface, engage the parking brake, and disconnect the battery for safety.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Remove the wheel using a lug wrench, ensuring all lug nuts are safely stored.

3. Remove the Brake Components

Remove the brake caliper by unbolting it from the bracket; support it with a bungee cord to avoid stress on the brake line.
Take off the brake rotor from the wheel hub.

4. Remove the Wheel Bearing

Remove the axle nut using a socket and breaker bar; consult torque specifications for reference.
Detach any retaining clips or bolts securing the wheel hub assembly.
Carefully pull the wheel hub assembly off the spindle; you may need a slide hammer if it's stuck.

5. Install New Wheel Bearing

Clean the hub and apply a thin layer of grease to the new bearing.
Press the new wheel bearing into the hub assembly using a bearing press or appropriate tool.
Reinstall the hub assembly onto the spindle and secure it with the axle nut.

6. Reassemble Brake Components

Reattach the brake rotor and caliper, ensuring all bolts are tightened to the manufacturer's specifications.
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower the Vehicle

Remove the jack stands and lower the vehicle back to the ground.
Torque the lug nuts to the specified value in a crisscross pattern.
