NHTSA ID: 10091423I just got the car home 2 days ago so hopefully this weekend get it on the hoist and have a look and try a few simple things and see what i can see. I may take it to the stealership if i cant resolve it or i find something that warranty will cover. I do have a friend that works there in parts and we deal with them regularly so that may make this a little smoother. Thanks for the update , it gives me hope. Also i suspect there are many who forgo the internet and have gone to the dealer and successfully had their cars repaired so it is possible that the poll is skewed somewhat.

SSM 45938 - 2015-2017 Mustang Driveline Vibration At Highway Speeds
Some 2015-2017 Mustang vehicles may experience a driveline vibration directly related to a vehicle speed of 70-100Kmh (50-70Mph) and is perceived as a tremor in the floor pan, seat track, or steering wheel and may be heard as a rumble, hum, or boom. Before replacement of any parts be sure to verify the concern with a road test and visually inspect the driveshaft for damage, undercoating, incorrectly seated universal joints, rotate the driveshaft by hand to feel for any binding or end play in the universal joints. If no concern is found check and correctany tire balance issues using Loaded Hunter Road Force® Method. If a concern isstill present balance the driveshaft using the Mastertech® Series MTS 4000 Driveline Balance and NVH Analyzer. Refer to Workshop Manual Sections 100-04,200-04Aand 205-01. Use labor operation 1007D and any appropriate combinations.

2015 - 2017 CAR: ZG MUSTANG (S550)
I'm not a mechanic but here's what it took for the dealer to fix mine:
Step 1 - Check for out of round tires. If tires ok, proceed to step 2.
Step 2 - Road force balance the wheels. Index tires to rims if necessary. Road test. If vibration still present proceed to step 3.
Step 3 - Check for excessive play in driveshaft center support bearing and differential flange bearing. Repair if necessary. Road test. If vibration still present, proceed to step 4.
Step 4 - Index the driveshaft 180 degrees. Road test. If vibration still present, proceed to step 5.
Step 5 - Remove driveshaft and bring to a driveline shop for balancing. If driveline shop doesn't have the fittings to mount on their balancer, proceed to step 6.
Step 6 - Balance the driveshaft on the car using hose clamp method. Road test. If vibration still present, proceed to step 7.
Step 7 - Replace driveshaft with new redesigned part.
Or you could skip from step 3 directly to step 7. Also, somewhere in there you might want to neutralize the transmission, d/s center support bearing and rear axle assembly to correct for any driveline geometry issues.
This work was all done at the dealer (Mullinax Ford, West Palm Beach, FL). Not to scare you but it took me 6 months of back and forth to get it fixed or at least fixed to the point where it's tolerable. There's still a vibration between 80 - 85 mph but I can live with that.
Good luck!
