This was just discussed 2 weeks ago. Since you have a 1941. It probably has the old style steering arm and shaft where the steering arm clamps to the shaft. Do like Gene said and when you get to the steering arm you'll probably find it real loose on the vertical shaft. It can be shimmed with a piece of soup can for a temporary fix. When you get the time and money replace bearings, shims and key. IH used to have a kit to change the old style straight vertical shaft to the newer one that is tapered on the bottom NLA but all the parts are still available to make the change over. When I did mine it was about $150 for steering arm and the vertical shaft but when I finished it was tight and still is.
