2005 JD 4920 has steering issues. Steering got stiff once or twice but cleared up right away. And it works fine with autotrac engaged. Now it happened again but did not clear up. The oil is not getting through. We have tried a few things. We were told to try and Hold the boom raise switch in the raised position while steering, The steering works easily then, and the problem should be in the load sense circuit. If you find the problem to be related to the load sense meaning it works when running the boom Then the load sense shuttle valve(flow control hyd valve) in the combo valve is most likely faulty.
In john deere parts online this valve is #4. But it looks fine. There is a little ball inside that moves freely and all orifices are clean. Unless im missing something, I think it looks fine. I removed all other valves and orifices and all seem ok. So I am at a loss. Does anyone have any suggestions?
Thanks for any help
