What do you mean "joystick has gone bad" ? Maybe others can interpret that, but sorry that I don't know what has happened.. prolly I'm a bit slow on the draw..
What led up to the problem? any history that might help? what took place since it last worked?

I have a machine a decade or two older than yours, an ag CUT and not a modern TLB. That said, we had nothing but problems with our single lever joy-stick type loader controls. Given room and mounting locations, it is not a difficult task to replace it with an old style two-handle or three handle valve combo.
