Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, wheel bearing puller.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the negative battery terminal to avoid any electrical issues.

2. Remove Wheel

Loosen the lug nuts using a lug wrench.
Lift the vehicle with a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove Brake Components

Remove the brake caliper by unscrewing the caliper bolts with a socket.
Hang the caliper securely using a bungee cord or rope (do not let it hang by the brake line).
Remove the brake rotor by unscrewing any retaining screws and pulling it off.

4. Remove Hub Assembly

Remove any dust caps or retaining clips from the wheel hub.
Unscrew the axle nut (if applicable) using a socket.
Use a wheel bearing puller to extract the hub assembly from the steering knuckle.

5. Inspect and Replace Wheel Bearing

Examine the old bearing for signs of wear or damage.
Clean the bearing housing in the hub assembly.
Install the new bearing by pressing it into place using the bearing installer or appropriate tool.
Reassemble the hub assembly, ensuring proper alignment and torque specifications are followed.

6. Reassemble Components

Reinstall the rotor and secure it with retaining screws.
Reattach the brake caliper and ensure the bolts are torqued to manufacturer specifications.
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower Vehicle and Finalize

Lower the vehicle from the jack stands.
Torque the lug nuts to the specified value.
Reconnect the negative battery terminal.
