John Deere 8370R hydraulic diagnostics - This one ALMOST stumped me!

Going back to the 8370R that the customer is complaining of hard steering when turning on the end rows while planting. Got to love a good challenge! Continuing from part 1, I am back to replace the load compensation valve on the main pump that I could NOT get to adjust because the adjustment screw was seized solid. Got to get the main pump pressure up to continue diagnostics. One thing leads to another and I end up having to yank the duals off to make some pressure adjustments and replace the whole entire priority valve housing.
