Central ND | We have a 9520 that is making noise when we turn under load. When I say noise it almost sounds like a slip in a gear, very sharp and distinct. It only does it when we turn, to either direction and only under load, it even does it when the air drill is lifted out of the ground but it will not do it with nothing hooked up to it. I tried yesterday to make it do it in the yard but it won't, tried diff lock, brakes, etc, but no noise with no load. The rear differential was apart on this tractor a year ago, all rear driveline bearings were new at that time as well. We drained all the oil yesterday, both differentials and final drives, and transmission. There didn't appear to be any shavings or chunks in any of the oil, it looked like it was just put in, as bad as the noise is I fully expected to find chunks somewhere! I hope somebody has some ideas, until then the 8850 is back on seeding duty! BTW, this is a different tractor than the other one I just posted about. | |

Drive line noise in 9520 when turning under load?
