2. Remove the Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove the Brake Components

Remove the brake caliper by unbolting it from the bracket. Hang it using a wire to avoid stress on the brake line.
Remove the brake rotor by unscrewing any retaining screws if present, or pulling it off the hub.

4. Remove the Hub Assembly

5. Install New Wheel Bearing

Pack the new wheel bearing with high-quality grease.
Position the new bearing onto the knuckle and use the puller to press it in place, ensuring it sits flush.
Reinstall the hub assembly onto the new bearing.
Reattach the axle nut and torque it to manufacturer specifications (typically around 200 Nm, but check the service manual).

6. Reassemble Brake Components

Reinstall the brake rotor and secure it with retaining screws.
Reattach the brake caliper and torque bolts to manufacturer specifications.
Reconnect the ABS sensor wiring if applicable.

7. Reinstall the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
