The drive shaft is unloaded when you are cruising along at a steady speed and you lift your right foot ever so slightly so that the vehicle just begins to slow down. If you lift too far, the shaft will load up in the opposite direction and the noise may return.
Please attempt to reduce or eliminate the noise via your right foot, in the manner described, and report back.

When traveling at a steady rate any where from 40-65mph I get a high pitched noise. When I let off the fuel pedal the sound goes away and depress again and it returns. Is this bad wheel bearing? have something to do with drive shaft, differential?? Differential fluid has been changed, rear axles are new, rear brakes are new. This is my first post by the way.
