I already sent mine off to Tracy for repair.  But even if there is end play
in that shaft (which there is a little) it would not affect the flex plate.
The thrust bearings in the drive prevent the shaft from moving toward the
engine -- and even if it did move that way, it would be stopped by the
e-shaft.  Forward (in the aircraft) movement of the input shaft (as would
occur when the prop is pushing the engine) is softened by a nylon bearing
(Tracy has a name for it).  The movement is small(like .005), and has no
ability to affect the flex plate.
