Gene: I'm stumped, Hendrik is stumped; do you have any ideas about this? I have replaced every internal part in the steering box with new Case parts, even an NOS steering wheel shaft and worm - all new except for the shaft the steering-arm presses on to. Its taper is in excellent shape, keys and key-ways are sharp, the taper bore on the steering arm is perfect. The steering box itself is in good condition. There is no in/out play in the steering wheel shaft. After replacing all the parts, the steering wheel shaft has 1/3 turn of play in it. It's the same amount of play the steering wheel had with all original parts. It's a 1948 Super A. I'm not referring to play in the ball-joints or spindles. Turn the steering wheel one direction until it stops and it will take 1/3 turn the opposite way before the steering arm begins to move.
