i found my problem. the sink screw holding on the outdrive shaft was loose (forgot to thread lock it)
i also sanded off a bit off the bottum of the input shaft so I could really clamp it down around the bearings and the diff box to make sure it would not wobble at all.
the front is now perfect with no wobble at all. but no matter how hard i try to clamp down the rear it will still wobble up and down a tiny bit. not side to side just up and down.
do i have to worry about this?
thanks.
