I purchased my 04' F150 back in December 2003. I started to notice the clunking on stopping and going. The dealer did the TSB of lubing the yoke. It definetly helped a little but it's not the cure all. Now just recently (2X so far) I have gotten the 55mph vibration. It lasts for about 5-10 minutes then it's gone. I have a feeling that all the troubles are coming from the slip yoke. I feel it's binding up.

A friend of mine owns a GMC Dinali and had the same problem but a lot worse them mine. After 3x with GMC and a lot of unneccesary lube time. GMC came out with a TSB to replace the slip yoke with a Titanium yoke with titanium splines. He never had a problem again. [Why can GMC find the trouble and Ford can't. Or is it they don't want to spend the money. If I could find a replacement for mine I would gladly pay out of pocket to fix my troubles. The dealerships don't really care.

Thanks.

 

Keep taking it back to them until the problem is fixed after about the 4th or 5th try tell them you would like the form to envolve the Ford DSB. (DSB Defective Service Board)

vibration only lasts 5 or 10 minutes? Are you sure it's not flat spots in your tires? It is cold up there...
