Well I had a 04 screw that had the nibble at 60 and 70 dealer road forced balanced and it fix the problem.

Now I have a 05 and after I rotated the tires I developed the nibble. I just got my truck back from the dealer and they road forced balanced these also. (and changed my f150badges) I plan on keeping this truck for a few years will this problem come up after every time you rotate the tires? If that is the case that just sucks. It took my dealer A.C. Collins ford 2 days to perform this service. I quess I'll half to wait and see when I hit 12,000miles to rotate.
Just wondering!

 

If you do, I would think there is a tire problem. I have rotated my tires with almost every oil change, 3500 miles, since my dealer keeps giving me a coupon that takes the cost to $10. I have 22,3oo miles on the tires and they have never been rebalanced.

 

Just curious. What is a nibble? Is it the same as a wobble?

 

Exactly, let go of your steering wheel at certain speeds and it moves back and forth.
