not sure of what you mean. here is a pic of my rear outdrive. the pin fits with very little play. the drive pin will move when the suspension moves up and down. but my lower suspension arm moves moves front to back about 1/2 a mm. i will try shimming this later. i only run stock so i have not seen anything that could cause any problems. but then again my car is a little loose in the rear. i will shim the arm this weekend.
