Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and the parking brake is engaged.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts on the wheel where the noise is coming from.
Lift the vehicle with a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove Brake Components

Remove the brake caliper by unscrewing the caliper bolts using a socket set.
Secure the caliper with a bungee cord or rope to avoid straining the brake line.
Take off the brake rotor, if necessary, by removing any retaining screws.

4. Inspect and Replace Wheel Bearings

Use a socket set to remove the hub assembly bolts.
Take out the hub assembly and carefully inspect the bearings for wear.
If bearings are worn out, replace them with new ones. Use a bearing press tool if needed to install new bearings.
Ensure bearings are properly greased before installation.

5. Reassemble Components

Reinstall the hub assembly and torque the bolts to the manufacturer's specifications.
Reattach the brake rotor and caliper, ensuring all bolts are securely fastened.
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Finalize

Lower the vehicle back to the ground and use a torque wrench to tighten the lug nuts to the specified torque.
Reconnect the negative battery terminal.
