6125 M john deere steering noise

[spurs]

This tractor has a grinding sound in steering , it's actually noise made by the fluid going through the steering but almost sounds like a growl, has anybody else had this problem, John Deere has not been able to help me figure this out

Not sure which pump you have, but I suspect you might have cavitation of the oil. That means the pump is sucking air from somewhere. Make sure the clamps on suction hoses at the pump are tight. If they are, you could have a cut oring on one of the suction side fittings. How many hours on the tractor? Has it done it since new?

Tractor is new only about 200 hrs but JD can't figure out.
