Cheesehelmet, normally you can tell a wheel bearing because it will change pitch or go away all together when you turn to the right or the left at speed. Also, spinning your wheel by hand will often reveal a bad bearing, and you can use the shop test to determine (grab the top and bottom of the wheel and see if it moves) but I had a bad bearing but the wheel didn't seem to move when I did that.
I've tried the "shop test" that you described and there's no apparent looseness. I recently inspected my right rear hub (took the disk off) and noticed that when spinning the hub it's not perfectly smooth (it's a little gritty at times) and it barely makes half a rotation when I give it a hard spin (I suspect that's normal though).
For those of you who've had bad bearings, can you describe the sound? When you say it's "loud" does that mean that it's loud enough to make it hard to talk to your passenger? My problem is that the noise I hear isn't very apparent, most of my passengers don't even notice it (even when I point it out).
