When I asked Ford to diagnose the same problem the only thing they did was install a steering stabilizer. Check to see if your has one I'll bet it doesn't. Look into a steering stabilizer and it should go away. You can pick up one just about at any parts store or your favorite online shop. That is what they did to fix the problem for the shop here cause I took it to them under warranty. At that time there were no TSB's on the problem. Don't know if there is any yet. Should be recalled after the amount of people having issues. Hope this helped.
