Rotating sound.

I have a sound that goes to the speed of the vehicle, it’s a rotating whoosh whoosh/oscillating sound(similar to the sound of a bad wheel bearing). That being said, all hubs front and rear have been replaced, rotors pads and calipers have been replaced, brand new drive shaft. The only thing I can think of would possibly be the dif? I’ve tried to have my wife drive and I move around the seats trying to pin point where it’s coming from but can’t seem to besides a strong feeling it’s in the rear, furthering the possibility of a dif.

At this point it’s making me crazy.
