Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secured with jack stands.
Disconnect the battery to avoid any electrical issues while working.

2. Remove the Wheel

Tools Required: Lug wrench, socket set
Loosen the lug nuts on the wheel.
Raise the vehicle and remove the lug nuts completely.
Take off the wheel to access the brake components and hub.

3. Inspect Wheel Bearing

Tools Required: Torque wrench, pry bar
Remove the brake caliper (if necessary) by unbolting it and hanging it safely (do not let it dangle from the brake line).
Remove the brake rotor to access the hub assembly.
Inspect the wheel bearing for signs of wear or damage. Look for pitting, discoloration, or roughness when rotating the bearing by hand.

4. Replace the Wheel Bearing (if necessary)

Tools Required: Bearing puller, press, or hub assembly tool
Remove the wheel hub assembly if the bearing is integrated. Use a bearing puller to extract the old bearing.
Clean the bearing housing thoroughly.
Install the new wheel bearing using a press or suitable tool, ensuring it is seated properly.
Reassemble the hub assembly, rotor, and brake caliper, torqueing bolts to manufacturer's specifications.

5. Reinstall the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified torque value.
