Ever since i converted to 4 speed, from a c6, ive noticed some slop in the drivetrain. It is noticable when going from decelerating with the engine holding the truck back, to accelerating, or vise versa. I had the trans and tranfer case out when i did the swap, and didnt notice any slop there. So im wondering if its in the rear end. I also recall noticing it when i had the c6. Could this be cause by a worn ring and pinion? or what?
