I have a 4890 that the rear wheels will pivot erratically sometimes. The front and rear sensors check out ok. I have hooked the dioagnostic box up to the tractor and everything checks out ok. Any ideas?

Clean up and center rear steer valve. Slightly decrease sensitivity adjustment at control panel. Check grounds as others have suggested.

Forgot to mention, every wire that needs to be grounded make sure it is grounded. Dad stayed mad all day yesterday b/c steering was in and out for the rear. at the end of the day it was just the ground wire that needed tightening.

totally redone the fuse box on our 4890 like john said, also make sure the sensors are the correct ones, dealer gave us the sensor for the back of a 4690 and it was to short so back tires would rarely respond.

I had the same problem with a 4690 & the problem was with the fuse holder tucked away in the console.
