Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery to prevent any electrical issues while working.

2. Remove the Wheel

Use a lug wrench to loosen the lug nuts while the vehicle is still 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 Caliper and Rotor

Unbolt the brake caliper using a socket wrench and hang it using a bungee cord to avoid straining the brake line.
Remove the brake rotor by unscrewing any retaining screws if present, and carefully slide it off.

4. Remove the Hub Assembly

Remove the axle nut using a socket and breaker bar.
Depending on the model, you might need to remove the tie rod end, lower ball joint, or suspension components to free the hub assembly.
Unbolt the hub assembly from the steering knuckle and pull it off the spindle.

5. Replace the Wheel Bearing

If the bearing is integrated into the hub assembly, replace the entire hub.
If the bearing is separate, use a bearing puller to remove the old bearing from the hub.
Clean the hub area and install the new wheel bearing, ensuring it is properly seated.

6. Reassemble the Components

Reattach the hub assembly to the steering knuckle and secure it with bolts to the specified torque.
Reinstall the brake rotor and caliper, ensuring to torque the caliper bolts to the manufacturer's specifications.
Put the wheel back on, hand-tighten the lug nuts, then lower the vehicle.

7. Final Checks

Tighten the lug nuts to the manufacturer’s specified torque after lowering the vehicle.
Reconnect the battery and conduct a final inspection to ensure everything is secure.
