Steering sensitivity at highway speeds
 

I am new to Fords, but I bought my wife a 2010 Expedition Limited 2wd a while back. I have been impressed with it. However, at highway speeds, the steering seems very sensitive. I have to drive very carefully to keep from jerking everyone's head around.

It is completely stock, Michelin tires, 20" wheels, never wrecked, with about 135k miles. Everything seems good. Is the steering sensitivity just a Ford thing, or could there be something wrong with the speed sensitive steering?

The steering sensitivity is actually supposed to be reduced the faster you go. Assuming no front end parts are worn, I'd be more inclined to think the front end alignment if off, specifically the toe adjustment.

I just had the alignment checked, and was told it was okay. Any other ideas?
