The main source of play in these boxes comes from either the column thrusts ( using the threaded adjuster), the interaction between the worm and wheel ( via the adjustable cover) and play in the drop arm shaft and its bush. There is also the interaction between the drop arm shaft and the thrust button, which can be affected during " enthusiastic" removal of the gear from the shaft taper. Above all, do not expect to be able to remove ALL free play or it will stiffen up on lock. The art is in hitting the right spot between play and overtightness, and I'll guarantee it will feel different on the road than on the bench. This is a can of worms and I've never bottomed mine.
