Well, while doing my brakes. I tried to shake the CV on the left and right side. Seems like the right CV has more up and down play then the left side AND the rears are solid. Something there a issue? Which might explain rough acceleration still? Thanks.(also my brakes feel much better Rears were glazed and rear rotors had chip marks and alot of sliders were rusted one was rusted solid in the front, torch took care of that one and I could see the uneven wear on the pads, just cleaned up the rust and greased....)

The CV's should slide in an out to compensate for axle travel. Lots of play in the CV indicates wear. I've only seen one come apart over the years and the outter shell was still intact.

Maybe. The two front are non-oem and are over 100,000KM old. In the rear I have one original and one reman(recently replaced). The play is at the differential side.
