Sal I don't think it is that. My right foot is still bandaged up from foot surgery so have not dug into it yet. but have seen this, when in 4 hi & in gear the half shaft spins @ the cv joint from the tc to the cv joint. the shaft on the other side of the joint does not move (this is all on the pass side)

thats my guess right now, once I have walk more then a few steps before popping perkecets like candy I will be able to tear in to see.
