Solution

1. Preparation

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

2. Remove Wheel

Loosen the lug nuts using the lug wrench while the vehicle is still on the ground.
Lift the vehicle with a jack and secure it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Wheel Bearing

Visually inspect the wheel hub assembly for any signs of wear or damage.
If the bearing is suspected to be worn, proceed to remove the hub assembly.
Remove any retaining clips or bolts securing the bearing to the hub.

4. Remove and Replace Bearing

Use a bearing puller to extract the worn wheel bearing from the hub assembly.
Clean the hub surface where the new bearing will be installed.
Apply a small amount of bearing grease to the new bearing.
Using the bearing installer tool, press the new bearing into place, ensuring it is seated correctly.

5. Reassemble and Torque

Reattach the hub assembly to the vehicle, securing it with the retaining clips or bolts.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then use a torque wrench to tighten the lug nuts to the manufacturer’s specified torque value.
