Hauling silage wagons with the 8010 this weekend, and started to have trouble steering.  Tractor wanted to drift to the left, and was slow/unresponsive to turn back to the right.  Eventually, I lost all steering to the right.  

Reading information on the forum here, someone had a similar problem with an 8030, and the likely culprit was the orbital steering motor at the end of the steering wheel.  I am guessing, that after 9000 hours, a seal has blown, or some orifice is plugged, not allowing flow to the right turn valve.  

I see both used and new motors for sale online (Dealer, TractorParts ASAP, etc).  I also see that there is a seal kit part number shown on the partsbook.  

If this is a seal issue, I can replace the seals for less than $100.  If this is a bigger problem, the motor looks to be about $700 after the core charge is returned.  

What do you all recommend?  Rebuilt, replace, or am I barking up the wrong tree of symptoms?  

Thank you
