Tubasteve is right on about those Subie bearings. In the shop I worked at 12 yrs ago we were not allowed to replace just one wheel bearing on Subes. Too much of a chance of comeback. So we did both at frt or rear of car. And about 50K miles was the due date on these. And funny how resonance works. Could've sworn it was the frt bearing when it was the rear, etc.
Another tip... Can you creatively extend your stethoscope by taping it to the car where you suspect noise?
If it is really loud, a vacuum hose held to ear might be all you need.
