Vibration between 50 & 70 mph

[ultimate warrior]

You don't understand nor ever will understand it's process. You think it's simple 10 min job when it's not.

I thinking no matter what car brand you have you will complain. Haven't yet made perfect car and never will be one made. You're not prefect either get off your high horse. Too bad there wasn't quality control on people LOL

what FordService needs to be doing is giving us updates on issues that she knows are common and are plaguing a large enough portion of users.

assuming that our subset is representative of all owners, then half of the polled users have vibration in their cars. the other half have lucky driveshafts or dont know that they have the issue (minimal).

this, to me, logically, is a big issue. the members dont need their cases elevated, the QC concern is what needs to be elevated, and echo'd by FordService.

if i was wrong there would not be a 60 page thread.

fix it.

Most of 60 pages is ranting like you what you're doing. AGAIN you have no idea what it takes to fix it just complaining.

Guys - please don't derail the thread of subject matter via arguments.

Ultimate Warrior -

Many of us agree with what you are saying, more so those of us who had to go through a lengthy process to come to a resolution.

If your vehicle exhibits the problem - take it to your FSC and get the diagnosis process started. That is the only way to resolve it. You also need to contact Deysha on here so she CAN get your case assigned to your Regional Ford CSR. Once that happens, then you have more leverage than just being a "walk in" customer to your FSC. It also gives you the leverage to procuring a Loaner vehicle.

Even if there were a TSB that contained a resolution, your car would not be fixed "on the spot". The Techs would still need to follow the diagnosis format within the TSB. Also even if parts X, Y, Z are noted in the TSB as being defective or possible parts that *might* need replacing, the FSC's across the country aren't going to stock those parts in large quantities. That's inventory and inventory costs the dealer money, more so if it's just sitting and not being used.

A TSB only gives guidelines and possible solutions to fix a common problem (like this), but it doesn't give anyone priority for the fix, nor does it guarantee an in/out same day fix. It's NOT going to be a same day fix for many.

I've been the biggest advocate for all of you - trust what I am saying in my replies and follow the leads I'm giving you. As 357CobraII stated, it's NOT a simple fix, it just isn't, even if a TSB existed right now, unfortunately it just requires time and patience.

Put it this way - sure I was frustrated and ticked my brand new car had to go in 4x and with total days at the FSC being almost a month - but I was happy they locked me into a Loaner. The FSC Service Manager, my Case Worker and Deysha were extremely great to deal with in being able to work the issue AND get it elevated further within Ford.

The Engineers ARE working the issue... It's clearly documented in my work order.

^^^ This !!

If you read a TSB you would see it too is a process or road map for the tech to verify the issue then isolate what needs to be replaced. Some even have a full blown flowchart of test this, did it fail/vibrate (whatever) yes/no, then the next step depending on the result.

I agree that Ford SHOULD be stepping up to provide some better documentation to the dealers on this, but it's almost sounding like they do have something internally documented and will step the tech thru the process. The key (as always) seems to be finding a dealer with a cooperative SM + techs who are trained to use the vibration tool to work thru the steps and diagnose the car.

Getting Deysha involved so you can be assigned a Case Worker & case # also seems to get the dealer to take the complaint more seriously.

On day one I have had a problem with this. I was unable to get it up to these speeds when test driving, however on the way home with the car is when I noticed it. I will be bringing the car back when I have another day off.

Adam, you may have already done so (didn't scan thread too see) but make sure you contact FordService when you take the car in.

We are really lucky to have someone from Ford monitoring these forums !

Anyone know what happens in the case of the car is a lease and they keep it for months (like the other guy on here?) I would think that would be grounds for suspending some lease payments, but I'm guessing Ford Credit wouldn't share that perspective.

Probably have to submit to moderator.

Well, the arbitration was decided in my favor for a replacement. :cheers: As relieved as I am, I'm still a bit disappointed that it had to come down to arbitration. I guess it's now down to waiting to see what the details will be about the replacement vehicle. 2015's are in very limited supply, especially V6 verts, so I'm not sure what my options will be. I just hope Ford steps up a bit more than they have to this point to something resembling the right thing.

I've maintained the high ground until now, but will step down for a moment. Please clue in that these are not the trucks you work on, and that many of us do not tolerate the quality levels and piss-poor attitude that wrench turners like yourself subscribe to and subject us to. Some of us have standards, and hold people (and companies) to those standards. I am definitely happy I don't drive something you work on, and am happier yet that I don't need to rely on timely, quality service for one as part of my business since it is obvious that I would go out of business waiting for a fix.

What you just posted shows you don't know what you're talking about LMAO. Try again

Order a 17. When I won my arbitration on a 15 EcoBoost and Ford couldn't locate a 15 GT with options I wanted I Special Ordered on 16. Why the hell do you want another 15? At least get a 16.

When my 15 got lemoned, they special ordered me a 16. It was delivered to the dealership 27 days later!

Jim, when did you take delivery of your '15? How long did you have it before it went in the shop?

Congrats that they decided to replace it. If they have to buy back a few lemons due to this issue I would think that addressing it would be a very high priority.

TO bad your ignorance is showing. You don't even know me so this piss poor attitude is you. I'm just pointing out real world I guess if I just agreed with you and people like you I be "COOL". Quality we have some of best and standards that surpass auto industry. Drivers live in these trucks so they expect the best. Like to see auto industry surpass million miles and keep going like trucks do. Car would be junk with rough roads that trucks take a beating on. I wouldn't want anything you touch with your ignorance BS.

You seem to hate trucks and people who work on them. You should respect trucks and people who work on them. EVERYTHING you own has been touched by a truck. If trucking industry went on strike for a week it would bring this country to it's knee's.

OK, Dropped off car, had some other things done. Shop foreman rode in car, felt the vibration. Car went to technician who returned the car quickly. and gave it a "it vibrates and is normal". There is not yet a fix.

I was afraid of this.

If I have to resort to fixing this problem myself I will post step by step procedures of how to solve it. It IS solvable, but it is painful. Might be easier in the long run, though.

Anyone in the Los Angeles area have a shop bay with a lift I can moonlight in to fix my car? It will be for a good cause...!!!

To summarize this thread - as of today, 3/15/2016, 49,000 views, almost 1100 posts.

172 out of 389 cars polled (44%) reported the vibration. I am not sure if this is representative of the entire production lot of Mustangs, but it certainly is an eye-catcher. Most of us probably have the GT - that's why more of them are reported as having the vibration, because they are more common on this board.

A) Seems like a large (exactly how large ?) portion of the 2015-2016's might be affected with a drivetrain vibration issue.
B) The majority of the vibrations are due to a mismatch between 1) pinion flange runout/balance tolerances and 2) the amount of intentional, factory-introduced driveshaft imbalance that is used to offset it. That is what the yellow dots are supposed to indicate is where to line it up so that the runout is offset with imbalance.
C) Replacing the differential sometimes works. The diff. assy. should come with a new flange. Also, if past fiascos with the 99-03 IRS mustangs have any value at all, Ford should know by now that you HAVE to send out a new diff. assy. together with a matching driveshaft, or else the platform will not rotate smoothly, and thus problem is not actually addressed. It's not usually a "parts quality" problem - it's an assembly issue due to mismatches in manufacturing tolerances (See B above). Maybe somebody mixed up a bunch of driveshafts.

Thus:
D) Replacing the driveshaft alone almost never works (See B above - DS and flange are supposed to be a matched set)
E) Rebalancing a driveshaft to be actually "balanced", and mating it to a flange with incompatible runout will definitely not solve it, unfortunately.
F) Replacing both the pinion flange and the driveshaft "should" work, if the mismatch issue has been identified and addressed at Ford, and they are sending out compatible diff-DS sets. Unless -
G) The vibration is due to a different issue that is not related - it's all about "the feel". Tire imbalance or half shaft problems will be a "shimmy". Drivetrain vibration is a drone or a roar that is reminiscent of a prop-driven airplane sound, and is dependent only on vehicle speed and/or load.
H) The Ring and Pinion set is rarely the culprit.
I) The problem can be addressed by enthusiasts who have the proper tools and facilities. It is trial and error, however, so expect to spend quite a bit of time troubleshooting it.


You guys (and gals) please update the thread if you find out good info that a TSB or solution is available.. Deysha (FordService) hints that something is in the works at Ford, but only the dealers will know. Thus, the rest of us that are waiting on the fix will only know from you.
