rear end noise

Hello all, I'm having a problem with a noise in my rear end. It is a humming sound, like a bad bearing. I've replaced both wheel bearings,seals and fluid and still have the same noise. It's at low speeds cruising around 45mph and gets louder and more consistant at 55mph and up. I can also feel the vibration on the floor at these speeds. Someone was telling me that it could be my pinion bearing. Any thoughts.

could be the drive shaft universal joints also. take drive shaft loose from rear end. jack up tire a couple inches and turn pinion to test it, then wiggle the universal on the drive shaft to test it.
