I have a 4040 that had a leaking steering motor seal above tie rods.I replaced it to only have it blow out again after start up. It was suggested to me that I overhaul the seals in the steering motor so I did. This took care of the problem, but after start up wheels turned all the way to left. When I move steering wheel, wheels go all the way in opposite direction. Turn steering wheel again other way ,wheels go 100% the other way. What did I mess up
