I was brushing hogging and making a turn, the steering wheel lifted a couple of inches, then dropped back in place. No issues after that. When I finished, decided to check and see if the nut holding the steering wheel had come loose. Popped the cap, the nut was tight, lifted slightly on the steering wheel and it didn't drop back into place. Now I can't get it to drop in and can't steer. Looks like at one time there may have been a rubber boot covering the shaft where it enters the steering box, but it is nonexistent now. Any ideas as to what is going on? No issues with seering until this happened. Can't find anything on the web about it. Any ideas appreciated.
