Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench.
Ensure the vehicle is on a flat surface and the ignition is off.
Disconnect the negative battery terminal for safety.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which wheel bearing is being replaced.
Secure the vehicle with jack stands to prevent any movement.

3. Remove the Wheel

Use the lug wrench to loosen the lug nuts, then remove them completely.
Take off the tire to expose the brake components and wheel hub.

4. Remove Brake Components

Remove the caliper by unbolting it from the mounting bracket (typically two bolts).
Suspend the caliper using a bungee cord or similar to avoid straining the brake line.
Remove the brake rotor by unbolting or sliding it off the hub.

5. Replace the Wheel Bearing

Remove the hub assembly from the knuckle, which may require unbolting several bolts.
Carefully press out the old wheel bearing using a bearing press or hammer and drift.
Clean the hub area and press in the new wheel bearing, ensuring it's seated properly.

6. Reassemble Components

Reinstall the hub assembly back onto the knuckle, securing it with bolts to the manufacturer’s torque specifications.
Reinstall the brake rotor and caliper.
Mount the wheel back on and torque the lug nuts to the manufacturer’s specifications.

7. Lower the Vehicle

Remove the jack stands and carefully lower the vehicle back to the ground.
Reconnect the negative battery terminal.
