Two possibilities come to mind:
1. problem in the valve - you can determine if that's the cause by reversing the hoses for that function - if it now goes to the left and sticks, it's most likely the valve.
2. problem in the piston. A piston has come loose from the rod, or a that rod has broken may result in the symptoms - usually the piston/rod will extend to the end of travel and then refuse to retract.

I have not worked on a Ford 4500 before, but I had a similar sounding problem that turned out to be a missing nut in the BH control lever linkage that activates the valve.
