Saw some other threads about similar sounds and just starting a new thread in case nobody responds to those older threads. 02, 150,000 miles Whirring sound from frontend, much more so from the drivers side than passenger and louder inside the car than outside that I can tell. I seem to feel the vibration a bit in the gas pedal or floorboard, very lightly, kind of like a grinding. Sound seems to start around 35, goes away at speed, 50 or so. What I feel in my foot also goes away at highway speeds. Seems some roads this is more prevalent than others but could be speed on those roads is related. I am running a rather aggressive tire, not super such though, and I've had those tires on there for several years with no whirring noise (I do need to rotate though).
