Put the tape on the vertical edges of the windsheild, under the black plastic molding. I used to get a rattle sound, and this fixed it. You can see if it is loose by tapping your finger on the molding, you can hear and feel if it is loose.

I'm pretty sure there is a detailed thread on here with pictures and everything.

But iwillnc is talking about wind noise accociated with his roof. Moving the light/roof bars will change how the wind acts against your sunroof, sunroof wind deflector, roof bar tracks, marker lights, etc. That is all I can think of why it would change with removal of roof bars. Make sure everything is tight if you are getting a rattle...
