'91 Legacy Wagon, 2WD, Auto tranny. I have a funny driver-side noise (sounds like a worn bearing) that becomes evident when driving above 30 mph. Doesn't appear to be related to the engine, because it is undetectable at idle, but still right there in neutral above 30 mph. It is there regardless of steering direction, and seems to increase intensity/frequency with speed. I've poked around underneath and in the engine compartment and can't find anything rubbing or that would otherwise cause a noise like that. CV joint & boot seem just fine on that side.

 

The noise appears to be coming from somewhere just in front of the steering wheel.

 

Any thoughts?

I would think bearings, even though it sounds like its behind the steering wheel. That's how mine sounded when it started going. Later it was worse, and sounded like I was driving a roaring set of snowtires.
