Look up SSM 46767 in this thread - that was the last and latest SSM from Ford which required the dealers to replace the driveshaft for 2015-2017 S550’s with the 6R80 trans. I think the part # was in that document.

It’s been a while since I last posted in this thread - and 2 years since my prior 2016 was bought back by Ford - that’s how I finally got rid of the driveline vibe... best decision too.

That exact same fix worked wonders on my '16's vibration issues too :fistbump: :wink:

I believe there is some detail back up earlier in this thread, I apologize but I don’t have it. You can specifically look for “vibration dampener“ Or “vibration damper”. I made mine a lot better by unbolting the driveshaft and reattaching it 180 deg. relative to the original position on the flange. Then I traded ithe car in last year. Maybe someone else can chime in with part numbers, which I would do, but I never had to buy them.

Seems like the biggest challenge, which I ran into also, was getting a dealer that will acknowledge that the problem exists. And that’s after driving the car, I had several they just said they couldn’t feel it (yep, that’s you, Galpin Ford of Los Angeles, and Ford of Orange) Shame!

If you have a cooperative service department at your dealership, that’s 80% of the battle for getting it addressed.

I took my 2017 GT in last year for the driveline vibration, was told my tires were cupped(they were not). Vibration is worse this year, and consistent between 50-70. Just had new tires put on last week so the "cupped" tires excuse is eliminated. Working my way through this very long thread, hopefully I find some info to help fix it myself or to help the dealer repair the issue.

JK - My post #3456 might help:

I hope it helps. If you need any more info, DM me.

Thanks!, I did find your post earlier. I will be using this information. The new Michelin Pilot Sport 4S, GREAT tires, highly suggest them. Drove through a torrential downpour a few days ago and had no issues with hydroplaning or grip through corners. The tires removed any other vibrations, which made the driveline vibration more noticable.

Hi I have questions.
Post of June 3, 2018, No. 3445
There are photos of spare parts. Please write me the order numbers.
Which Ford Mustang model it was mounted on? What engine and gearbox? What year of production?
Did it solve the vibration problem?
Thanks a lot for the information ..

So are the 2018-19 cars vibration free- and is the AC evap problem fixed now? I fixed my 2015 EB vibration problem by getting a Challenger but I'm looking at a 2018 EB with 11K miles on it for cheap money. Also, are the 10sp auto smooth in the Mustang? My 2018 F150 was horrible and never shifted well. Always lurched and clunked into the lower gears. After the Mustang and F150, I'm pretty leery of buying another Ford.

Well the results are in;

The factory steel sleeved right rear Diff. bushing needs a counter bore to allow engagement of the male portion of the damper center hub.
I may decide to machine the male nipple off the hub in the near future.

For reference this is the same for both Dampers.
15-17 Ford (FR3Z-4A263-A) https://www.quirkparts.com/oem-parts/ford-damper-fr3z4a263a
2018 Ford (JR3Z-4A263-B)

Wish I had better news.
The JR3Z-4A263-A Damper is used on the 2018 models
The FR3Z-4A263-A Damper was earlier models
Here is a close-up of the: FR3Z-4A263-A Damper
Weight: 4 lbs, 3.1 oz

I have done some experimenting with these, I am currently using two dampers, attached to the rear diff bolts.

Here is a close-up of the: HR3Z-4851-B Flange
This is a lot nicer looking piece than what was used on the previous models. (They were un-painted, and rusted very easily/quickly)

I wasn't able to get my FR3Z-4A263-A Damper installed on my 17 GT. The spare tire well is in the way.

Now that you mention it, I haven't read about anyone with a 2018+ complaining of driveline vibration. So maybe Ford finally figured it out and incorporated something new.
I'm sure the Dual Mass Flywheel and Dual Clutch offered new in 2018 for the Mustang GT V8's helped with some engine/driveline vibration.

Doubtful, the drivetrain vibration is not related to engine or clutch harmonics.
