My 2008 had this problem until I put a front receiver on it. I posted about this before and most agreed that it had little to do with it, but I haven't had the problem once since then.

 

No Ford has not fixed the issue. Its sad that Ford has used the same front suspension since '05 and has no updates during that time. Some dealers even refuse to believe the issue exists.

 

As the thread finally got down to.. It seems the typical reasons for the wobble, no matter what year of Superduty truck are:

1. Worn or damaged steering stabilizer.
2. Worn or damaged tie rod ends.
3. Damaged track bar or bushings.
4. Damaged or worn front wheel hubs.
5. Worn front shock absorbers.
6. Bent or out of balance front wheels/tires. (usually occurs at certain speeds)
