Recently my car has started to make a whirring noise when accelerating. It seems to happen under moderate acceleration when the car is warmed up to operating temps.

Maybe a bad bearing but the pitch changes with each gear change.

To me it sounds like it may be an accessory driven part because when I disable the a/c and radio I can't hear the noise. (no it isn't radio static) ...so at this point the noise is somewhat erratic.

The next service for the rear brakes is in about 5000km so hopefully the car will fix itself (not likely) or the part that's making the noise fails or gets worse making it easier to diagnose.

Anyone else have a whirring noise?
