Solution

1. Preparation

Tools Required: Socket set, torque wrench, jack and jack stands, wheel chocks, screwdriver, hammer, and bearing puller.
Safety Warnings: Always wear safety gloves and goggles. Ensure the vehicle is on a flat surface and properly secured with jack stands.

2. Lift the Vehicle

Sub-steps:
- Park the vehicle on a flat surface and engage the parking brake.
- Place wheel chocks behind the rear wheels.
- Use a jack to lift the front or rear of the vehicle (depending on which wheel is being serviced).
- Secure the vehicle on jack stands for safety.

3. Remove the Wheel

Sub-steps:
- Loosen the lug nuts with a socket wrench before lifting the vehicle.
- Once the vehicle is lifted, remove the lug nuts completely and take off the wheel.

4. Remove the Brake Assembly

Sub-steps:
- Remove the brake caliper bolts using a socket wrench.
- Secure the caliper away from the rotor using a bungee cord or similar tool (do not let it hang by the brake line).
- Remove the brake rotor by unscrewing any retaining screws if applicable.

5. Remove the Hub Assembly

Sub-steps:
- Remove any dust caps and cotter pins holding the hub assembly.
- Use a socket wrench to remove the axle nut.
- If necessary, use a bearing puller to extract the hub assembly from the spindle.

6. Replace the Wheel Bearing

Sub-steps:
- Press the new wheel bearing into the hub using a bearing press or hammer (ensure it is seated properly).
- Reinstall the hub assembly back onto the spindle.
- Replace the axle nut and secure it to the manufacturer’s torque specification (usually around 250 Nm).

7. Reassemble Components

Sub-steps:
- Reinstall the brake rotor and secure it with screws if applicable.
- Reattach the brake caliper and ensure bolts are tightened to specification (typically around 35 Nm).
- Reinstall the wheel and hand-tighten the lug nuts.

8. Lower the Vehicle

Sub-steps:
- Carefully lower the vehicle back to the ground.
- Once the vehicle is on the ground, torque the lug nuts to manufacturer specifications (usually around 120 Nm).
