I have a 2010 F250 King Ranch FX4. I have an odd problem that I am trying to get to the bottom of. We went on a 2,500 mile road trip last year and I noticed on the way home my steering wheel had worked it's way off center counter-clockwise at a perfect diagonal. I had gotten an alignment right before we left and it was perfect center at that point.

I took it back in when I got home and had a tire rotation and another alignment. Within a week the wheel was off again to the same degree, counter-clockwise at a perfect diagonal.

Two weeks ago... tired and annoyed of driving like this, I crawled under the truck and adjusted the steering wheel to center via the drag link adjustment. I tightened everything down tight and this lasted all of three days.

Any ideas what would cause this? Tires are wearing normally, alignment checks out and it tracks straight. I do see some grease like leakage where the pitman arm meets the top of the drag link and again have some small grease where the drag link connect to the passenger side tire. I lifted the front end and tried to move/wiggle the tires and I have no movement... everything is solid. The truck never wanders when on the road... steering wheel is just off.

Truck only has 90k on it of highway miles and an easy life thus far. I am not hard on the truck.

 

Look in at the steering box pitman shaft, the small space right above the steering arm. I had the same problem and if I had looked right in there I'd have seen the shaft was ready to break. I lucked out and it finally broke in a parking lot, things could have been much worse !
