Remove the axle nut using a socket and breaker bar.
Use a wheel bearing puller or slide hammer to extract the wheel bearing from the hub assembly.
Inspect the hub for any damage or corrosion.

5. Install New Wheel Bearing

Clean the hub area and apply a thin layer of grease to the new bearing.
Press or tap the new bearing into place using the appropriate tools.
Reinstall the axle nut and torque to the manufacturer's specifications.

6. Reassemble Components
