Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, torque wrench, socket set, wheel bearing puller, and press.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery if working on electrical components.

2. Remove Wheel

Use the lug wrench to loosen the lug nuts while the vehicle is on the ground.
Jack up the vehicle and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Remove Brake Caliper and Rotor

Tools Required: Socket set, brake caliper tool.
Remove the bolts securing the brake caliper and carefully hang it using a bungee cord (do not let it dangle by the brake line).
Remove the brake rotor by unscrewing any retaining screws and pulling it off.

4. Remove Wheel Hub Assembly

Tools Required: Socket set, wheel bearing puller, torque wrench.
Remove the axle nut using the appropriate socket.
Disconnect the hub assembly by removing the bolts that secure it to the suspension components.
Use a wheel bearing puller to extract the wheel hub from the knuckle.

5. Inspect and Replace Bearing

Check the inner and outer races of the bearing for damage or excessive wear.
If the bearing is damaged, press out the old bearing using a bearing press and replace it with a new one.
Torque Values: Refer to the service manual for proper torque specifications when reassembling.

6. Reassemble Components

Reattach the wheel hub assembly, ensuring all bolts are torqued to specification.
Reinstall the brake rotor and caliper.
Reattach the wheel and lower the vehicle.
