We have had the same problem. Dumped both duals off one side last year. It was a miracle that we didnt tear something up. We found that slowing down on the turns helped. But the our problem was that when the tire repair guys put new tires on, they didn't follow Deere's wheel lug torque procedure. We got suspicious when we broke 3 impact sockets getting the other wheels off to check the lugs. Sure enough they were all super tight and cracked. Since we torqued them down correctly and slowed down on turns, we've had no more problems.
