Yes, so it relax and take tension out of it this best way I can say it.

Very very good info. That's a thorough paper trail and troubleshooting procedure. Happy to hear they were able to fix it.

Lots of information in the Repair Orders shown, but hard to follow exactly what order everything was done, and if some of it was done simultaneously. Obviously, there can by many factors involved, and those factors might even be different for different models (GT, V6 & Ecoboost). Misaligned motor mounts and/or exhaust system might show up more in the Ecoboost than in the GT or V6 for instance.

Would the vibration have went completely away if they "neutralized" the engine mounts and exhaust system hangers first before working on the driveshaft, flanges, etc? Hard to say.

I have not had a chance to get on here over the last week - however I will have some information to post up later today/tonight. I picked up my vehicle on March 2, after nearly a 3 week stay at the Ford Service Center. It's fixed - and it feels and drives better than the first day I took ownership of it. :)

Stay tuned.....

Also, for those who have legit claims, that have been verified by your Dealer - don't let others in this thread derail it with ill will and non-value added gibberish.

(DEYSHA - thanks for all of your help and getting the issue elevated with my vehicle as you have for others. I know I may have been aggressive in my approach on here with some of my responses - but it was in no way aimed directly at you. It was more of a "hey, you're an insider there at Ford, so let's elevate this to Engineering Team faster since the issue existed on 2015 and carried over into 2016 models." ----> THANK YOU!)
Thank you for the kind words, Cobra Jet! I appreciate it!

****BAD RESOLUTION TO MY VIBRATION*****
Was escalated to the Regional Customer Service and while they are good at returning email they apparently are not good a forcing a replacement of the two wheels that require 7 ounces of weight to zero balance. Without tires the wheels require more than four ounces.

The replacement wheels cost $1,412.18 which includes core charges, yes ford wants the old parts back so they do not get re-sold. Now you see why they don't want to touch this issue...

Bottom line, I will pursue the Dealer and Manufacturer in CA small claims court, my time and trouble and anguish is worth the maximum $10,000. However, class action against Ford is a possibility if some want to PM (contact) me.

Thanks Deysha for the escalation, guess the western region has got the memo for good customer relations.
You’re welcome, majtom94.

Got it! Thanks, amilhazes!

Yes, exactly. It was directed by the FSE and Engineering Team to loosen it (exhaust) up from all mounting points, let it settle and readjust as needed. Less tension on system near trans tunnel, floor pans and rear IRS.

The same was directed by the FSE and Engineering Team for the engine - loosen engine mounts, run engine and let it "settle", then retorque engine mounts.

They also did the same with the trans mount prior to the engine & exhaust neutralization.

Would the vibration have went completely away if they "neutralized" the engine mounts and exhaust system hangers first before working on the driveshaft, flanges, etc? Hard to say.

The Feb 02 - Mar 02 (pages 1-10):
Those are the sequence of events. The very first page just lists the parts replaced, while pages 2-10 contain the actual events as they unfolded. The vibration was always a confirmed vibration by the Techs, the Service Manager and the FSE - so it was definitively diagnosed as being driveline related, thus the need for replacing the flanges and driveshaft.

After the flanges and driveshaft were replaced, the vibe had subsided but with the detection equipment, they were able to narrow the remaining vibes down to the engine bay. They checked crankshaft runout and that was the reason for removing accessory belts to narrow by accessory (IF there was an issue with an accessory or crank, they would then begin that type of analysis). Since there was no issue as noted, they moved on to the engine mounts and exhaust mounts. After neutralizing both the engine and exhaust, that was when all detected vibes ceased to exist while in the shop and once it was test driven.

Is my fix an "end all" to all others? Maybe, or maybe not. However, based on my case example and resolution this SHOULD help other Owners AND the Ford Service Centers with a quicker diagnosis and what to zero in on.

I would say to anyone who has a driveline vibe to print only my Feb-Mar pages 1-10 and let their FSC Service Manager read it over BEFORE they try to do it by trial and error.

The tires and rims were NEVER an issue - more so when the problem was persistent in a specific RPM and MPH ranges. But this is the first area the FSC's want to always look at first.

Got mine back late yesterday and the vibration issues are mostly gone, there is still a slight vibration between 53 - 58, but for now I don't see it as significant enough to tear further into the car. I never expected it to be perfect and it is a muscle car, so it's not going to ride like a Benz. Besides, car is just a few months old with 800 miles, so I have a lot of warranty time left to play with should it start to get worse or bothersome.

For what it's worth, what they did for me was:

1) local dealer - confirmed vibration issue, did the obligatory RF balance & found 1 tire that would not balance, confirmed DS was indexed correctly - tire ordered

2) local dealer - installed & balanced new tire, vibration still present, further testing pointed to DS being out of balance - DS ordered

3) local dealer - installed new DS, vibration still present, scheduled the car for more testing then canceled & said Ford Techline wanted Elder Ford (selling dealer) to take over

4) Elder Ford - car was there for a week
Tech confirmed vibration
SM arranged for loaner (I live 70 miles from them!)
test drove with vibration monitor which pointed again to the DS
Ford balked & did not want to cover another DS
Tech took a new, automatic GT off the lot, confirmed with the tool there was no vibration
pulled the DS off that car & installed on mine - test drive w/tool, vibration gone
swapped the DS's back - test drive w/tool, vibration returned
Ford relented and approved another DS
3rd DS installed, road tested with vibration tool - tested within spec
a few other minor issues I asked them to address were fixed
car washed & returned to me

In summary, hats off & a BIG shout out to the Tech's & SM @ Elder Ford. They were not going to let some desk jockey 1500 miles away from the issue deny a repair when their tools & experience told them the DS was still an issue. Definitely the best customer service I've had on a domestic car in a long time !

Must find dealership that has vibration analyzer . We have vibration analyzer here at work but they won't go off I find because they can't. I can't go off what another shop did have to start over especially with warranty work. They will ask to see how you got to point if you skipped part of T/S. If do they will denied claim in tell you do it right.

Goes to show that Ford has some out of spec drive shafts from whoever they source them from. Even the new drive shaft from their parts inventory was bad. :headbonk: Ford needs to come down on their parts source vendors for better QC.

Mine began the journey today, but there are some other issues that need to be addressed first (i.e. water leak around windshield, dash vents always blow warm air). Was able to demonstrate to the shop foreman the vibration, and he was experienced enough to know it was driveline related. Hopefully this bodes well.

Wish me luck.

Deysha, you have two PM's from me related to this issue, as requested. Sorry for the delay and thanks for looking out for us.

I've had several different ppl from Ford tell me they are easily damaged in shipping. I guess I'm showing my age, but I always thought a DS was a pretty heavy duty metal part that you'd have to beat with a sledge hammer to damage. Guess the new stuff is all light weight - apparently in several respects ............

As for the original one being bad, either there is a QC issue or they do not get handled properly @ the factory or some combo of those issues.

There was a sticker on my original drive shaft that said 'discard if dropped'.
