I think I found the problem.I pulled back the rubber boot up from the tilt steering column and looked at the mechanics of the steering when the wheel is turned and found there was a lot of play of a square rod mating to a female adapter on the tilt steering assembly.I removed the complete tilt steering assembly by removing only the 4 nuts that hold the whole unit onto the chassis,I did not need to remove the steering wheel. The entire unit came off with no problem about 5 minutes.The steering unit came off with the wheel attached and the square rod which was now exposed (called the adapter splined hub ) was attached to the chassis.It just fits into a geared female adapter on the front of the tractor. Both the adapter and the female clamp attached to the tilt steering assembly were worn.The adapter splined hub can be purchased for $32.50 but the clamp is part of the tilt steering assembly and can not be purchased.You must buy the whole steering assembly and that cost $452.00. So what I,am going to try to do is fill some of the area in the female clamp with some JB weld and file and sand to fill in the slop and on the adapter which is steel I will fill some of the area with welding material and file and sand.The clamp is made of aluminum so I can't weld material into it.I have some pictures of what the two units look like.
