UPDATE: The expedition has around 8,000 miles on it now and I got fed up with this problem - especially after driving an '08 expedition and my dads new 07 F150 that had a COMPLETELY different steering feel. My wife claimed I was crazy, she could not notice a thing and thought it drove great, but having owned numerous Fords over the years, it did not feel right to ME. So, I took it back to the dealer, the service guy I was dealing with vowed to fix it so he and the mechanic put thier geads together and agreeed on the only part it could be. They ended up replacing the "steering gear". I asked, are you talking about the rack, they said no, supposedly this is a seperate part...... Anyway, this completely fixed it, I could tell as sson as I was ulling out of the aprking lot with it, they also performed the transmission TSB and I am love this SUV now.
