Solution

1. Preparation

Gather tools and necessary parts.
Ensure the vehicle is parked on a flat surface, and the engine is off.
Disconnect the battery for safety.

2. Remove Wheel and Brake Components

Tools Required: Lug wrench, socket set, jack, jack stands.
Loosen the lug nuts before lifting the vehicle.
Lift the vehicle and remove the wheel.
Remove the brake caliper and rotor to access the hub assembly.
- Use a caliper tool to compress the caliper piston if necessary.
- Secure the caliper with a wire or hang it to avoid strain on the brake line.

3. Remove Hub Assembly

Tools Required: Socket set, impact wrench (if available), torque wrench.
Remove the hub assembly retaining bolts.
Carefully separate the hub assembly from the steering knuckle.
If applicable, disconnect any speed sensor wiring or components attached to the hub.

4. Inspect and Replace Bearing

Inspect the bearing for wear or damage. If noise is confirmed, replace the bearing.
Tools Required: Bearing puller, press (if needed).
If the bearing is pressed into the hub, use a bearing press to remove and install the new bearing.
Ensure proper alignment and fitment during installation.

5. Reassemble Components

Reverse the removal steps:
- Install the new hub assembly and secure it with the retaining bolts.
- Reinstall the brake rotor and caliper.
- Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications.

6. Final Checks

Reconnect the battery.
Test the vehicle for noise and ensure proper functioning of the wheel assembly.
