How much free play is there in your steering? It is important that this be tested with the wheels straight ahead. So drive straight ahead for a good distance and stop. Then, when parked with the wheels straight ahead, how far do you turn the steering wheel before you feel resistance as it attempts to turn the front wheels? Up to about 2" in either direction should be okay. If more than that and you need to visually check the drag link and tie rods ends for slop as someone moves the steering wheel back and forth. If those look tight (no slop) then you probably have an excessively worn sector. Try tightening the adjustment on the steering box, but not too much; leave a little slop.

If none of that fixes the problem, it is likely that the steering wheel is a little loose on the steering shaft, along with a woodruf key that is not tight in the slot on the shaft or within the wheel; or missing. Get a new one for a few bucks and be sure it is snug on the shaft and within the wheel. Tighten the steering wheel nut right down. Don't know the torque spec.

I had the same problem of shifting wheel centering after removing and replacing the steering wheel on my '41. Pulled the steering wheel and found the woodruf key laying in the top bell of the steering column. The key was too loose a fit to the slot on the shaft, and when I installed the wheel, I knocked the key out and did not notice. A new key was dressed with a file to fit snugly, and the problem was solved. Could have been much worse!
