I have a L1500 That the steering box has been pretty Sloppy for a while. Recently the issue started where I can turn it to the right just fine but when I to turn it to the left the steering shaft just rises up like it is unthreading. Is there some kind of shear pin or Key that may be broke? I know I am going to have to tear it down to see what is wrong but I do not want to spend a fortune to rebuild the whole Steering Box. Just thought I would get some insight from the Pro's before I start.
