Just went for a drive at 10 PM when it is quiet on our street. The sound
seems to be most prominent at 35 MPH. When I cruise in neutral it does not
seem to happen, BUT the sound is so faint that it is hard to tell when and
under what conditions it occurs. maybe I am too much of a perfectionist.

I guess I will just have to wait for the sound to mature (or immature.)

I will keep checking.
