there are a few spots that can cause the play. One is the steering wheel connection to the tilt mechanism. The next is the tilt mechanism shaft and the third is the tilt to steering box connection and bushing. I think you might need to remove the wheel to check it and the tilt mechanism for play and probably the tilt mechanism itself to check for play in it or the steering box. There is a bolt that tightens the tilt to steering box. That might be loose or worn but bushing failures are more common issues.
