Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely raised on jack stands.
Remove the wheel by loosening the lug nuts with a socket and ratchet.

2. Remove the Brake Caliper

Sub-steps:
- Remove the caliper bolts using a socket.
- Carefully detach the caliper from the bracket and support it with a bungee cord or rope to avoid strain on the brake line.
Tools Required: Socket set, brake caliper tool
Safety Warning: Do not let the caliper hang by the brake line.

3. Remove the Rotor

Sub-steps:
- If necessary, remove any retaining screws on the rotor.
- Slide the rotor off the hub.
Tools Required: Screwdriver, hammer (if rotor is stuck)

4. Remove the Hub Assembly

Sub-steps:
- Remove the dust cap to access the hub nut.
- Use a socket or impact wrench to remove the hub nut.
- Disconnect any ABS sensor wires if applicable.
- Remove the hub assembly from the spindle.
Tools Required: Socket set, impact wrench, screwdriver
Safety Warning: Be cautious of sharp edges on the hub assembly.

5. Install New Wheel Bearing

Sub-steps:
- Press the new bearing into the hub if it's a separate unit or replace the hub assembly as a whole.
- Ensure proper alignment and secure it using the hub nut to the manufacturer’s torque specifications (typically around 150 Nm).
Tools Required: Torque wrench, bearing press (if applicable)

6. Reassemble Components

Sub-steps:
- Reinstall the rotor and secure it with any retaining screws.
- Reattach the brake caliper and tighten the caliper bolts to specification.
