Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and turn off the ignition.
Disconnect the battery to prevent any electrical issues.

2. Raise the Vehicle

Tools Required: Jack, jack stands, wheel chocks.
Lift the vehicle using a jack and secure it with jack stands.
Place wheel chocks behind the rear wheels to prevent rolling.

3. Remove the Wheel

Tools Required: Lug wrench, torque wrench.
Loosen the lug nuts on the affected wheel while the vehicle is still on the ground.
Remove the lug nuts completely and take off the wheel.

4. Remove the Hub Assembly

Tools Required: Socket set, breaker bar, impact wrench (if available).
Remove the brake caliper and bracket to access the hub assembly.
Disconnect the ABS sensor (if equipped) and remove any retaining clips.
Unscrew and remove the hub assembly bolts.
Carefully pull the hub assembly off the spindle.

5. Inspect and Replace the Wheel Bearing

Inspect the wheel bearing for signs of damage or excessive play.
If the bearing is faulty, press the old bearing out of the hub using a bearing press.
Install the new wheel bearing into the hub, ensuring it is seated correctly.
Reassemble the hub assembly back onto the spindle and torque the bolts to manufacturer's specifications.

6. Reinstall the Wheel

Reattach the brake caliper and ensure all components are secure.
Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value.

7. Final Checks

Reconnect the battery and check the functionality of the ABS sensor.
Inspect for any leaks or issues before taking the vehicle for a test drive.
