I have a 04 F250 PSD CC SB 4X4 which I purchased new on 6/1/04. From the start it had vibration problems. I now have 3,600 miles on it and have had it in one dealership once and another three times. The second dealer changed out two alum wheels and said it was within Ford specs for vibration. Still vibrated. I then replaced the stock BFG's with new Bridgestone revo's and probably the ninth balance job. Now it only vibrates from about 68mph up but still has a very annoying vibration at higher speeds. Any suggestions, or are these vibrations inherent in these vehicles?
Thanks for any help.
