Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, bearing puller, grease, and new wheel bearing assembly.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any electrical issues during the repair.

2. Remove Wheel

Loosen the lug nuts using a lug wrench while the vehicle is on the ground.
Lift the vehicle with a jack and secure it on jack stands.
Completely remove the lug nuts and take off the wheel.

3. Remove Brake Components

Remove the brake caliper by unscrewing the caliper bolts (typically 14mm or 17mm).
- Warning: Support the caliper with a bungee cord or rope; do not let it hang by the brake line.
Take off the brake rotor by removing the retaining screws or any clips holding it.

4. Remove Hub Assembly

If necessary, remove the axle nut using a socket (usually around 30mm).
Disconnect any speed sensor wiring if applicable.
Unscrew the hub assembly bolts (typically 12mm or 14mm) and carefully pull the hub assembly off the spindle.

5. Install New Wheel Bearing

Clean the spindle and surrounding area thoroughly.
Apply grease to the new wheel bearing and press it into the hub assembly if it is not pre-installed.
Reattach the hub assembly to the spindle, ensuring it is seated correctly.
Tighten the hub assembly bolts to the manufacturer's specified torque value (consult service manual for exact specification).

6. Reassemble Brake Components

Reinstall the brake rotor and caliper in reverse order of removal.
Ensure that caliper bolts are tightened to manufacturer specifications.

7. Reattach Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and torque the lug nuts to the specified value (usually around 80-100 ft-lbs).
