rear end noise

Aloha, Great site - newbie trying to figure it out - sorry if i screw up...

My wifes Impreza (1997 automatic w/only 30,000 mi.- its a small island ) has an occilating hum/whir coming from the rear - I'm thinking differential or CV Joint - her father is thinking wheel bearing. Tires are new and LOOK ok. Notice it best on the freeway (thats 55mph here) and NOT uphill (loaded) @ same speed.
ANY ideas???

Generally bearings make a constant deep growl louder with speed, gears are noisy under load or decel. Driveline ujoints can make the oscillating sound, a belt breaking in a tire can also. I'd either rotate the tires or swap them out first..cheap and easy. Gene

Thanks Gene. Yeah, I didn't look close enough - there was a slight scalloping inside edge of rear left tire (6 months after having alignment done @ Sears - UGH!). You were right, that was it. GC
