Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a flat surface and secured with wheel chocks.
Disconnect the battery for safety.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Remove the wheel associated with the suspected bearing issue using a socket set.

3. Remove the Brake Caliper and Rotor

Tools Required: Torque wrench, socket set.
Remove the caliper bolts and securely hang the caliper using a bungee cord or wire (do not let it dangle).
Remove the brake rotor.

4. Remove the Wheel Hub Assembly

Tools Required: Impact wrench, bearing puller set.
Remove the retaining nut or bolts securing the wheel hub.
Use a bearing puller to extract the wheel hub from the knuckle.

5. Inspect and Replace

Inspect the wheel bearing for wear or damage.
If necessary, press out the old bearing and press in the new bearing using a hydraulic press.
Clean the hub assembly and apply grease to new bearings as required.

6. Reassembly

Reinstall the wheel hub and secure it with the retaining nut/bolts to the manufacturer's torque specifications.
Reinstall the brake rotor and caliper.
Reattach the wheel and lower the vehicle back to the ground.
