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 correct any tire balance issues using Loaded Hunter Road Force Method.
If a concern is still present balance the driveshaft using the Mastertech Series MTS 4000 Driveline Balance and NVH Analyzer.
Refer to Workshop Manual Sections 100-04, 200-04A and 205-01.

We have a 2017 Mustang GT, purchased in Australia. It has now traveled around 2000 km. There is a noticeable drive-train vibration /thrum on smooth roads at 80-100 km/hr. At higher speeds there is no noticeable vibration. I selected neutral but no difference, which tends to eliminate the engine being the source of the vibration. it ruins the driving experience.
Same here on my 2017 Mustang GT in Germany. It really ruins the fun. The dealer says that’s how it is. They can’t improve it. The Mustang is relatively soft, so this is some kind of resonance frequency.
Let me know is you found a cure.
