Hum noise at exactly 65mph

[cop on my back]

So I received a call from the service advisor from the dealer , driveshaft was replaced and the noise was still present . Now they believe the noise is coming from the differential , so there waiting for the parts to arrive , I should have the car back by Monday , Hopefully that solves the problem . I will keep you guys posted on what they exactly replaced once I find out

Interesting. Mine is going in on Wednesday for a couple days to figure it it out, will report back.

Hey there, I know this is an old thread. This is actually my first post. I've been a mopar guy all my life and just made the switch to a Ford. I have a 2020 Ecoboost, fastback with the pony package and 19" wheels with Pirelli all season rubber. Car only has 6k miles on it, and I have the exact same 65mph hum. Comes on at exactly 65mph, then goes away as soon as I go faster. Did you ever figure out what caused this? I'm super meticulous and this hum is ruining my enjoyment with the car.

Sorry you are having this problem (and haven't gotten any responses to your first post). I had a similar problem with my '15 and it turned out to be the driveshaft. Has your dealership offered any explanations or even tried to diagnose?
