Check this link out. Ford has the evap test that will happen when the truck is off. It will make a mild humming noise. But I've never heard one that loud. 90% of people never hear it. I'm not 100% sure. But it might have something to do with that. Just an idea.
Does the sound go away after driving for awhile?
Does the sound happen every time after you shut the engine down?
