After the inspection, take the vehicle for a road test to listen for the noise under different driving conditions, which can help you pinpoint the issue more effectively. If the rattling persists, consider utilizing diagnostic tools like a mechanic's stethoscope to isolate the noise to specific areas of the vehicle.
