odd grinding noise coming from truck
Hi people, a few days ago I came from a long 1600mile trip. After that I used the truck to go camping with a few friends about 4 hours away from home. At some point during the camping trip I noticed my truck making an odd grinding sound at low speeds in the front end. The higher the speed, the less apparent the noise and at 45mph, the noise can barely be heard. Almost the same noise a truck makes when it has heavy threads on it's tires. I figured maybe my tire pressure was too low, but at 37.5 PSI, they seem fine to me. IT got a bit worse by the time I got home to the point where i could feel the very small vibrations on the steering when going at very low speed (15 mph), so I jacked the truck and checked everything. Tranny fluid, front and rear drive shaft fluids, etc. Front brakes are getting there but have a little life left. all front components are tight and when I hand-spin the wheels no odd sounds or resistance can be felt. My tranny is working fine, when I put it into 4 wheel drive, all seems good. The sounds have no consistency on whether or not the brakes are applied.
It's a very strange noise as it's very consistent with the speed i'm going at. As I said, it feels like very rough tires going on very hard road or a bad gear somewhere. I keep thinking it may be either the tires or the front driveshaft that has a bad gear but why would my tires make such sounds so suddenly, and as for the gear, when hand spinning the tires slowly or quickly, I get no odd feeling or sound, and it the front wheels work superbly off-road still.
Does anyone have any idea what may be causing this?

It SOUNDS to me like yes it also could be that. But I tugged and pulled both front hubs in all directions and have zero movement. Is there a way I can look or verify if my bearings are shot?

I'll take everyone's word for it and say it's the drivers side bearing assembly. God knows how much longer it'll last at this point.
These can be purchased anywhere, but any suggestions as to what brand I should purchase?

the only advise here would be go with some good ones, dont skimp out on the cheap ones to save a buck. i really have no preference as where to buy them. i usually get everything from advanced auto parts since its close to me. IMO, i would go ahead and replace both driver and passenger sides while you are at it

My s10 blazer did that for a few weeks and I just rode it out. It would get REALLY LOUD as I sped up and then at like 45 or 50 It would CLUNK and stop doing it until I slowed back down to about 35 and it would do it again. It eventually stopped doing it. Either the problem quit or the 2 pieces grinded until they wouldn't hit anymore. Either way it was a self fixing problem for me.
I was thinking it wasn't disengaging all the way. Eventually switched to a manual actuator instead of vacuum. That being said. COULD it possible be the Actuator not disengaging all the way?
Does yours do it ONLY in 2wd too?
