Up and down is fine as there is play until the turbo has oil and is spinning.As long as there is no in and out your good.

Cause im not going to read this thread anymore...

Rebuilt turbos, even NIB turbos can have shaft play. It is more normal then most think(this thread proves it). Put it on the car, let it cycle some oil in there and the play should be less noticed if not gone. The shaft and the bearings can not be so tight as to where there is no movement, if that was the case youd just feed shavings from your turbo to the engine.
