Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts from the wheel.
Remove the wheel and set it aside.

3. Remove Brake Caliper and Rotor

Unbolt the brake caliper using a socket set and hang it securely using a bungee cord (do not let it hang by the brake line).
Remove the brake rotor by unbolting it from the hub assembly.

4. Remove Wheel Hub Assembly

Remove any dust caps or retaining clips from the hub assembly.
Unbolt the hub assembly using the appropriate socket sizes.
Carefully pull the hub assembly away from the knuckle, ensuring no damage to surrounding components.

5. Install New Wheel Bearing

Press the new wheel bearing into the hub assembly using a bearing press or suitable tool. Ensure it is seated evenly.
Reattach the wheel hub assembly to the knuckle, ensuring it is properly aligned.

6. Reassemble Components

Reinstall the brake rotor and torque the bolts to the manufacturer's specifications.
Reattach the brake caliper and secure it with bolts, ensuring it is torqued properly.
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower Vehicle and Final Torque

Carefully lower the vehicle off the jack stands.
Use a torque wrench to tighten the lug nuts to the manufacturer's specified torque value.
