I know this has been discussed before but here is what I am looking for. I want to find that low rumbling wind noise that sounds like the rear windows are rolled down while the front ones are rolled up. Now, mind you, the sound is not nearly that loud but it is the same type of sound.

Can you list the places I should check in order of importance?

What I am gonna do is tape up that area and head out to the interstate.

Rear outside windows, windshield, front grill, etc
