Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Torque wrench
- Socket set
- Wheel chocks
- Safety gloves and goggles
Ensure the vehicle is parked on a flat surface and engage the parking brake. Disconnect the 12V battery to prevent any electrical issues during the repair.

2. Remove the Wheel

Loosen the lug nuts on the affected wheel while the vehicle is still on the ground.
Raise the vehicle using a jack and securely place it on jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Remove the Brake Components

Remove Caliper: Unbolt the brake caliper using the appropriate socket and suspend it using a bungee cord to avoid stressing the brake line.
Remove Brake Rotor: Take off the brake rotor by removing any retaining screws or clips.

4. Remove the Wheel Bearing

Remove Hub Assembly: Depending on the design, unbolt the hub assembly from the steering knuckle. Take note of the torque specifications.
Take Out the Wheel Bearing: If the bearing is pressed into the hub, use a bearing puller to remove it carefully without damaging the surrounding components.

5. Install New Wheel Bearing

Install New Bearing: Press the new wheel bearing into the hub assembly, ensuring it is seated correctly.
Reassemble Hub: Reattach the hub assembly to the steering knuckle and tighten bolts to manufacturer specifications.

6. Reassemble Brake Components and Wheel

Reinstall the brake rotor and caliper, ensuring all components are securely fastened.
Reattach the wheel and hand tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the specified torque value.
