I figured the noise is coming from the differential because when I pop the shifter in neutral it immediately stops. But when im driving and its making the noise i can swerved to the right and it goes away, or if im on a road that has a right curve itll go away while im turning too. Just wondering if anyone has had this happen before

I would think wheel bearings because of it going away while i turn, but the fact that it goes away when i put it in neutral is weird
