Freeway "whoom whoom whoom" soft vibration at 55-60mph

Hey all, pretty much for as long as I've owned this truck, it has had a "whoom whoom whoom whoom" sensation that is audible and I can feel it through the floor slightly. I wouldn't even call it a vibration, more like a harmonic pulse of some sort that drives me nuts.

I just got back from the tire shop and had the tires balanced. They said a wheel weight had fallen off. Result: the truck feels maybe a tiny bit smoother, but the whoom whoom whoom whoom sound is still there.

Wheel bearing? Driveshaft? Rearend bearing? I'm at a loss...

Have you had a front end alignment done? If the alignment is off your tires could be worn in a way that they make that noise at highway speed whether they are balanced or not.
