If you're tracking a car pretty heavily, then you need to consider things like wheel bearings maintenance and wear items just like brake pads, rotors, tires, etc. I replaced a wheel bearing/hub in the Miata 10 days ago as well.

My problem actually went away after the TSB was done. I had mistaken that noise at the time for the same thing when it was something else that I took care of. 
Rust is a big and major factor with this noise for some of us.

Would the bearings know the difference between toe and camber? Seems the stresses would be similar, but could be wrong. I feel that camber increases wear on the bearings, and then once water gets in there the rust kills them (just theory again). Both my bearings failed not long after driving through heavy rain and lots of standing water. First one at 12000 miles (20% track), and the second at about 18000 miles (20 % track). And my rear heat shields were removed (don't know if this made them more exposed to splashing water).
I don't know how much water plays into it. The bearings have seals, and I don't remember my old seals being visibly worn. I just think they are under engineered.

When the bearings go, retorquing the axle nut will temporarily "fix" the problem. Be carefull of this, since it can fatigue the threaded shaft on the CV joint. If you have bearing noise, I wouldn't bother trying to retorque the spindle nut.

If you can afford to let the car sit on blocks for a week while you wait for parts, then remove the bearings and races to see if there is any scoring on the spindle. Otherwise, you should go ahead and replace the CV joint too. BTW, all 3 of the bearings I've replaced scored the spindle. Just because the wheel is turning, doesn't mean that the bearing didn't seize.
