I had the same problem but at 12 years old for my LT155 steering, ok on left but right spins and sometimes it would snag. After looking at it I noticed the steering sector would come in contact with the frame and I filed it down until it did not do it again. I am going to replace the belt, idlers, Steering shaft, sector and the bushings. I do not know if the steering was sticking due to the bushing wear and the sector coming in contact with the frame?
