Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the negative terminal of the battery (if applicable).

2. Lift the Vehicle

Use a jack to lift the front or rear end of the vehicle, depending on the affected wheel.
Secure with jack stands for safety.

3. Remove the Wheel

Using a socket set, remove the lug nuts and take off the wheel.
Set the wheel aside in a safe location.

4. Remove the Brake Components

If necessary, remove the brake caliper and rotor to access the wheel bearing.
- Unbolt the caliper using the appropriate socket.
- Support the caliper with a hook or bungee cord to avoid stressing the brake line.
- Remove the rotor by unscrewing any retaining screws if applicable.

5. Remove the Wheel Bearing Hub

Unbolt the wheel bearing assembly from the hub.
Use a specialized bearing puller if the bearing is pressed into the hub.
Carefully remove the old bearing, making sure not to damage the hub.

6. Install the New Wheel Bearing

Clean the hub and apply grease to the new bearing as per manufacturer specifications.
Press the new bearing into the hub using a bearing press or appropriate tool.
Reattach the wheel bearing assembly to the hub and torque bolts to manufacturer specifications.

7. Reassemble Components

Reattach the brake rotor and caliper.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the specified value.

8. Final Checks

Reconnect the battery terminal if it was disconnected.
Perform a visual inspection to ensure all components are properly secured.
