I agree with the jack up the car, grab tire at 12 and 6 and check for play, what you suggest I suppose is possible (but somewhat unlikely IMO) for a wheel bearing. True, that if they have play, the rotor will wobble between the pads, and sufficient brake pressure will "straighten" the wheel. Note that by play I mean like the wheel will wobble an 1/8", 1/4" and get worse as the bearing deteriorates, which *usually* takes 10s or 100s of miles (usual disclaimers apply). About half of the dozen or so wheel bearing failures I've encountered in my life made the groaning/turbine noise, while the other half was just what I perceived to be increased road or tire noise (these can easily be missed). With the turbine noise I've seen no play and even took the vehicle on a 1000 mile road trip, came back and still no play.
Anyway, I use Timken bearings. Heard bad things about Autozone bearings many years ago in that they were making noise soon after replacement, although no play, and maybe even failed early.
