High pitched whining

I have a this whining that varies according to truck speed and not engine speed. It started about two weeks ago when I went over a speed bump with a little speed. The front axle was relaced so it is not from the front. I looked under the truck and noticed a center support bearing. Do these give any problems? What else might it be?

could be the center support bearing but my rear carrier bearing went out. you can feel it in the floor board under your feet . this drove me insane until I found out what it was.I finaly jack up the rear end and set on jack stand and put in drive and got under the truck and found the noise was coming from the rear end
