Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the vehicle.

2. Lift the Vehicle

Use a hydraulic jack to lift the vehicle at the designated lifting points.
Secure the vehicle with jack stands for safety.

3. Remove the Wheel

Using a lug wrench, loosen the lug nuts on the affected wheel.
Remove the lug nuts and take off the wheel to expose the brake components and wheel hub.

4. Remove the Brake Caliper and Rotor

Remove the caliper bolts using a socket wrench.
Carefully slide the brake caliper off the rotor and support it with a bungee cord or similar device to avoid straining the brake line.
Remove the rotor by taking off any retaining screws if present.

5. Inspect and Replace the Wheel Bearing

Remove the wheel hub assembly by unbolting it from the suspension and steering knuckle.
Use a bearing puller to extract the old wheel bearing from the hub.
Clean the hub and install the new wheel bearing using a press or appropriate tool, ensuring it is seated correctly.

6. Reassemble Components

Reattach the wheel hub to the steering knuckle and secure it with the correct torque specifications (consult manufacturer specifications).
Install the brake rotor and caliper in reverse order of removal.
Reinstall the wheel and secure it with lug nuts, tightening to the manufacturer’s torque specifications.

7. Lower the Vehicle and Test

Carefully lower the vehicle and remove the jack stands.
Reconnect the battery and perform a test drive to ensure the noise has been resolved.
