Remove the brake caliper and bracket (if necessary) by unbolting it and securing it away from the rotor.
Take off the brake rotor to access the wheel bearing.

3. Replace the Wheel Bearing

Tools Required: Bearing puller, torque wrench, grease.
Use a bearing puller to remove the old wheel bearing from the hub.
Clean the hub assembly thoroughly.
Install the new wheel bearing, ensuring it is pressed in correctly.
Reassemble the brake rotor and caliper, torquing the bolts to manufacturer specifications.
