Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, socket set, bearing puller, and new wheel bearings.
Ensure the vehicle is on a flat surface and engage the parking brake.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which wheel bearing is affected.
Secure the vehicle with jack stands for safety.

3. Remove Wheel

Loosen the lug nuts using a lug wrench.
Remove the wheel and set it aside.

4. Remove Brake Components

Sub-steps:
- Remove brake caliper by unbolting it from the bracket.
- Suspend the caliper using a bungee cord or similar tool to avoid stress on the brake line.
- Remove the brake rotor by unscrewing any retaining screws or bolts.

5. Remove Wheel Hub Assembly

Sub-steps:
- Detach any components obstructing access to the hub assembly (e.g., ABS sensor, dust shield).
- Remove the hub assembly by unbolting it from the steering knuckle.
- Use a bearing puller to extract the old wheel bearing from the hub.

6. Install New Wheel Bearing

Sub-steps:
- Clean the hub and apply grease to the new bearing.
- Press or seat the new bearing into the hub assembly using a bearing installer tool.
- Reattach the hub assembly to the steering knuckle and torque the bolts to manufacturer specifications.

7. Reassemble Components

Reinstall the brake rotor and caliper.
Ensure all components are securely fastened and properly aligned.

8. Reinstall Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value.
