Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, torque wrench, wheel bearing puller, bearing grease, and socket set.
Safety Warning: Ensure the vehicle is on a flat surface and properly supported by jack stands before beginning work.

2. Remove Wheel

Loosen the lug nuts using the lug wrench.
Jack up the vehicle and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Remove Brake Components

Sub-steps:
1. Remove the caliper by unbolting it from the bracket using a socket wrench.
2. Support the caliper with a bungee cord or rope to avoid straining the brake line.
3. Remove the brake rotor by unscrewing any retaining screws and sliding it off the hub.

4. Remove Wheel Bearing

Sub-steps:
1. Remove the hub assembly by unbolting it from the steering knuckle (typically involves multiple bolts).
2. Use a wheel bearing puller to extract the old bearing from the hub if necessary.
3. Clean the hub area of any debris and inspect for damage.

5. Install New Wheel Bearing

Sub-steps:
1. Install the new wheel bearing into the hub assembly, ensuring it is seated properly.
2. Reinstall the hub assembly onto the steering knuckle, securing it with the original bolts. Torque bolts to manufacturer specifications (typically around 100-120 lb-ft).
3. Reinstall the brake rotor and caliper, ensuring all components are securely fastened.

6. Reinstall Wheel

Place the wheel back onto the hub.
Hand-tighten the lug nuts, then lower the vehicle back to the ground.
Torque the lug nuts to the specified value (typically around 100 lb-ft).
