I changed the steering box and pump on my car, set everything up exactly as it was but now I have a little bit of wondering back and forth in the steering. I saw someplace that the steering shaft hole had to be 13/16 away from the top of the coupling and that if it wasn't it could be an issue? I don't see how it could be since it slides up and down inside of the coupling. My coupling is tight (shoes seem fine) but there seems to be play in the box if the car is not running and the column is not locked when I turn it by hand on the shaft. When I start the car almost all of it goes away except maybe 2 degrees of the play, any suggestions on why I would have the play or wondering now? I would sure think that the new rebuilt box would be tight but then who knows about companies anymore. I got the box from OReillys it's a Master Pro.
