Default Humming noise from rear end, 2000 Tahoe

I have an annoying humming noise coming from the rear end of my tahoe. It sounds like a school bus constantling humming/howling. its a 2 wheel drive automatic. I recently changed the fluid in the rear differential which was almost a quart low but that didnt change anything. 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

i'm having that exact problem with my truck,i got an 2001 suburban 1500,2wd.. when i'm driving it makes an annoying humming sound,when i got off the gas,it stops... i was told that it may be the pionion rings in the rear,but i really wanna get it fixed a.s.a.p,because it's making me so frustrated with the truck... the previous owner obviously didn't take good care of the truck....when i find out exactly of the problem,i will let you know.... shonoff83@yahoo.com
