Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Raise the vehicle and remove the wheel.

2. Remove Brake Caliper and Rotor

Sub-steps:
1. Remove the caliper mounting bolts using a socket set (usually 14mm).
2. Carefully lift the caliper off the rotor and secure it with a bungee cord to avoid stress on the brake line.
3. Remove the brake rotor by unscrewing any retaining screws, if present.

3. Remove the Hub Assembly

Sub-steps:
1. Remove the axle nut using a socket (typically 30mm) and a breaker bar if necessary.
2. Disconnect any ABS sensor wiring if applicable (follow the wiring to the connector and unplug).
3. Remove the hub assembly bolts (usually 3-4 bolts) using a socket.
4. Gently tap the hub assembly with a hammer, if necessary, to loosen it from the knuckle.

4. Install New Hub Assembly

Sub-steps:
1. Place the new hub assembly into position on the knuckle.
2. Secure it with the hub assembly bolts, tightening to manufacturer specifications (typically around 75-85 ft-lbs).
3. Reconnect the ABS sensor wiring.
4. Install the axle nut, tightening to the specified torque (usually around 150 ft-lbs).

5. Reassemble the Brake Components

Sub-steps:
1. Reinstall the brake rotor, ensuring it is seated properly.
2. Replace the caliper and secure it with the caliper mounting bolts, tightening to manufacturer specifications.
3. Reinstall the wheel and lower the vehicle.

6. Final Check

Sub-steps:
1. Reconnect the negative battery terminal.
2. Pump the brake pedal a few times to ensure proper brake function before driving.
