Solution

1. Preparation

Gather the required tools and parts.
Ensure the vehicle is parked on a flat surface and secured with wheel chocks.
Disconnect the negative battery terminal to ensure safety.

2. Tire Inspection

Remove the hubcaps or wheel covers if applicable.
Check tire pressure and inflate to manufacturer specifications.
Inspect for uneven wear; consider replacing tires if necessary.

3. Wheel Bearing Inspection

Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel by loosening the lug nuts with a socket set.
Grasp the wheel at the top and bottom and wiggle; check for play indicating bearing wear.
If play is detected, proceed to remove the brake caliper and rotor for bearing access.

4. Replace Wheel Bearings (if needed)

Remove the axle nut using a socket set and breaker bar.
Extract the wheel bearing assembly using a bearing puller.
Clean the hub assembly and install the new wheel bearing, ensuring it is seated properly.
Reassemble the rotor, brake caliper, and wheel, torquing lug nuts to the manufacturer's specifications.

5. Reassembly

Reinstall the wheel and lower the vehicle.
Reconnect the negative battery terminal.
Perform a test drive to ensure the noise has been resolved.
