I'm pretty new to this, been lurking for awhile trying to research some of the problems I have and vibration at start off between 15-20 is about to drive me nuts. I took it in as I had vibrations from 15-20, 40-45, and then 65-70. The dealer told me that it was the mid-shaft bearing, is that the same as the carrier bearing? I use my truck for business so I could let them have it anylonger than they already had it, 3 days, which I lost 500 bucks due to them having to order parts. I should have just told them to order the parts and then I would bring it back to have the work done. Warranty is up due to being a used vehicle and it having over 100K, about 95K when the work was done. After they replaced the bearing, I still have the vibration at 15-20. The truck is an 03' crewcab F350 4x4 dually and all stock to my knowledge. Any thoughts would be be welcomed.
Thanks,
Greg
