Vibration between 45-55 MPH

[Frankis843]

Any further updates on this? I too am noticing a buzz/vibration that almost feels like it is vibrating the floor pan at speeds of 50-55 MPH and in a decent cross wind. I don't notice it when there is no cross wind. But the buzz certainly isn't constant as it comes and goes with no rhyme or reason I can detect.

I currently have 2022 Lightning and previously had 2022 Expedition. The vibration is the same on both. Had the tires balanced and rotated then finally replaced the wheels and tires, did not fixed the vibration. On the Expedition, I had changed the trans fluid (12quarts), changed the diff fluid, change the transfer case fluid, did not make a difference on vibration. In my opinion the common thing on these vehicles maybe the cv-axles. The cv-axle may not be balanced properly at the factory. Took it multiple times to the Ford dealership, the tech confirm the vibration, but could not figure it out. I was told other vehicles with the same year and mileage behave the same, so it must be normal.
