Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Use wheel chocks to prevent rolling and jack stands for safety.

2. Remove the Wheel

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

3. Inspect and Remove Brake Components

Remove the brake caliper by unbolting it from the bracket; support it with a bungee cord to avoid stressing the brake line.
Take off the brake rotor by removing any retaining screws.

4. Remove the Wheel Bearing Hub Assembly

Remove the axle nut using a socket and breaker bar; this may require significant force.
Unbolt the wheel bearing hub assembly from the knuckle and carefully detach it.
If necessary, use a puller tool to extract the hub from the knuckle.

5. Install the New Wheel Bearing

Clean the mounting surface on the knuckle to ensure proper seating of the new wheel bearing.
Press the new wheel bearing into place using a bearing press or suitable adapter.
Reinstall the hub assembly by reversing the removal procedure, ensuring to torque all bolts to manufacturer specifications.

6. Reassemble Brake Components and Wheel

Reinstall the brake rotor and caliper, ensuring all hardware is secure.
Put the wheel back on and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specification.
