I am replacing the rear diff box with new box,drive gear,bearings,and pinion. When assembled, the assembly does not turn smoothly, kinda choppy I guess you could say. There is no left or right movement possible with the ring gear and the pinion will move in or out only maybe 1 or 2 thousandths and really doesn't change how the assembly rotates. Is it because the gears are new and not seated yet? And if that is the case, should I shim the pinion gear in to fully mesh with the ring or allow it to move forward/backwards a little. The directions do not show any spacer so maybe it's an allowable tolerance? Am I over thinking this? Oh, It's a TBIII if that matters.
