    Just wanted to update, got the car back Monday. Will be driving the car to work for the rest of the week but so far so good. Still missing that vibration that I've felt for the past 16,000 miles.

    So what was the resolution or fix? I mean your post is good that you’re vibe free - but others will benefit from what your Service Center did for the repair. If you can post a copy of your work order that would help others immensely (just exclude the top section with personal info).

    Honestly they just re-balanced the driveshaft that my last dealer put on at like 6000 miles, simple as that.

    So far I've put about 250 miles on the car and its still good.

    Here’s some helpful S550 driveshaft specs and torque ratings for fasteners: 30312CD6-D199-47DF-8507-3311F3AD4C4E.jpeg D4A5E70D-1E61-4456-83D0-D303DE8BEEBD.jpeg 41F82FF7-D8D0-4CA1-B52E-84070C0D393B.jpeg

    Been driving mine to work all week, still smooth as glass. Finally ordered a Lund nGauge after 3+ years of owning the car

    My 15 V6 manual has been "fixed" 7 times now and the vibration just keeps coming back. On driveshaft #4 and differential #3. Only got 4000 km from the last driveshaft change. Have had the car 4.5 years and almost out or warranty. Has anyone had this problem fixed for longer than one year or 20,000 miles? I like the car as a daily driver but can't put up with this problem.

    Were all 7 fixes by the same dealer? If the problem goes away and comes back, something the dealer did made it go away. If it came back, there is a good chance they messed up the repair. VERY unlikely to get 7 (including original) defective parts in a row. It sounds like the odds are good the dealer(s) did something that contributed to the problem coming back. It's rare but not unheard of for dealers to intentional do that for the repeat business.

    If just one dealer is involved, or the last fix was by a dealer that did the bulk of the fixes, I would try a completely different dealer and insist that Ford get involved since the same thing keeps happening. Maybe something unusual about your particular car causes good parts to fail in use.

    Yes this is the same dealer and I know it would be easy to blame them but they are the best one around me. They have made a lot of money off this problem but I would think Ford would be on them for it I have dealt with others and not been happy with their work. Ford has been involved since the third repair and even given me one month free payment for my troubles ($500). I told the dealer that I will not accept only a driveshaft or a differential as a fix. I think I might have to talk to a lawyer or something. With all the vibration problems that so many seem to be having I can't believe there is not a class action suit started.

    Did you verify with the paperwork that they actually performed the TSB's? If not, might be time to sell if you cant deal with it anymore.

    I have never seen any paperwork and been told there are no TSB's nor can I find any online. If you know of one please forward me the info. I have had this problem since taking delivery of the car, I just thought it was a tire out of balance at first then got on the roller coaster ride from there. I shouldn't have to sell because Ford sold me a defective car, I won't get $hit all for a V6 stick anyway! Watch the documentary "A faster horse" on Netflix and near the end of it they show a boardroom meeting where the boss asks if the driveline vibration has been fixed which someone replies YES to save his job! This is a known issue.

    You did not get a receipt for the repair?

    I get a slight vibration at 80 mph. It's weird because I set my cruise at 70 didn't feel anything, smooth like on rails. moved up in 1 mph increments. at 78, 79 smooth. 80 mph. I start getting slight vibrations, I am talking very light. At 80 mph is when she starts hers. let got of the wheel she tracks straight. Its just a very light vibration. It makes the mirrors shake a little. I keep seeing everyone say between 50-70 mph. Mine is like 80 on the dot it starts. Ideas? I have done the same sitting in 5th gear. Set the cruise at 70 mph and went up mph at a time. As soon as 80 hits. mirrors start vibrating a little. I thought it was the tone of the aftermarket exhaust. Its a Borla cat back system. But I don't believe so. I have experimented at various rpms, gears, and speed combinations. It's definitely after 80 mph.
