Default Vibration/humming at all speeds/gears

Hey guys,

I have a vibration/humming coming from the rear of my 04 4x4.
Happens at all speeds and gears and slows down with the vehicle into a grinding noise. I replaced the rear dif with a reman last year and changed the oil today, no metal shavings, the oil was still clear gold like brand new, just some foam. The vent was a little plugged up so I cleaned that out as well. I'm thinking the noise is coming from the shaft somewhere. It's a one piece shaft. Any help is appreciated!

Have you checked for brake drag, including the parking brake?
