The thought about the box having an internal leak makes sense, but I don’t have faith in most shops to know how to watch for that. Most of the Saginaw problems manifest themselves as slop, but the stuff about replacing the column is bull. I’d do like the guys are saying and take it from the basics. If you couldn’t isolate the problem in the tires, I’d jack up the front end and check steering parts, ball joints, bearings, etc. You didn’t happen to see the alignment specs, did you? The toe should have been nominal for their machinery, but your camber should have been 1.5* positive, which is what it was from the factory in 1985-87. If it wasn’t close to that, something might be broken to have caused a shift.
