I had the EXACT same issue a few months ago, Couldnt diagnose it. Drove on it(big mistake) it was a bad wheel bearing. it ended up braking the axle too. Just got it fixed this saturday, Parts where $114 for new axle and wheel bearing, $20 to get the new bearing pressed and $0 for labor since a buddy of mine helped me do everything. I also changed the rear break pads ($35) because when the axle broke it rubbed my disc till it was bright red. have the wheel bearings looked at to be safe. It should only cost a few bucks to get new ones pressed.

I believe mine was, if i turned left there was no noise and if i turned right there was a noise. My bad wheel bearing was on the left side. So if there was pressure on it it would make that noise. So I believe you should be able to determine which is bad by that method. good luck

not yet, but i plan to try this tomorrow morning. i will just swap left to right. if the noise moves to the other side, then i know for sure it is the wheels/tires. if it doesn't move, it just eliminates that possibility. i'm actually hoping it is this, but i highly doubt it.

even if the tires have no 'visible' damage, feel the edges with your hand, a cupped tired can make a lot of noise. I have the same kind of sound right now as well and went to torque the axle nuts to find they had already been replaced and were extremely tight. I had an 30 year experienced tech drive with me and hes convinced its tire noise. Im in the same boat, i dont want it to be too late and the wheel bearing take out the whole hub.

it would be strange if the one tire was cupped though - air pressure is exactly the same on all 4 tires, and the rears are pretty much new. i've checked them every couple weeks since late november (just needed an excuse to test a new tire pressure gauge). but i won't rule this idea out just yet.
