Noise increasing with MPH (40 MPHish loud)

Had a noise pop up the other week that increases with MPH, becomes audible with increasing speed and you can start to hear it at ~30, max noise ~40 MPH, starts to taper off as you get faster as the wind noise / road noise starts to drown it out. Happens in gear or out of gear / independent of RPM. Was hoping it was one of my winter tires slipping a belt, but it's still there with summer ones (at least lower volume).

Anyone have anything similar / any common issues people are having with axles/bearing above 100k / 8-10 years?

It may be a wheel bearing starting to go south.

Could it also possibly be a differential bearing on it's way out?

it's gotten louder over the past 200ish miles (haven't driven it much)

that's the in neutral noise I hear ~32-33MPH

put it on stands today & ran it in first and listed with stethoscope at the wheel centers left/right (heard nothing) and then on trans case (heard lots of **** that I can't say sounded but have no reference to know good vs bad)
