JD Hydraulic steering pump weak and grinding

[jwjsr]

do i drive it till it dies? it's on a JD f650 Z-Track zero turn, wondering if i drive it till it dies vs fixing it now would save any $. Oh, and i am assuming it is the pump and not something in the wheels it drives. I haven't messed with the freewheel valve, is it adjustable in a way that might stop the grinding? thanks for looking
