Ideas on noise source - light fluttering sound at 70mph
I have a fluttering noise that seems like its coming from behind the dash or beneath the driver side wiper. It only happens at speeds of 70mph or above. It sounds like something is flapping lightly or fluttering. I have secured anything I can find in that area under the hood that was loose but its still there. Crosswinds or buffeting seems to make it louder.

Just wanted to give you a bump

Like someone has put it before "its like driving a brick with a sail on top". In a JK, and any Wrangler for that matter, the wind noise will increase as the speed increases, and the points for wind to ingress are infinite. We can chalk this one up to "A Jeep thing..." I just got done driving from Omaha to PA, and I can stear hear the noise in the hotel :lol:

I put some duct tape on the plastic screen over a couple of the slats in the middle outside vent in front of the windshield....I think I found it....but will know more definitely once I drive home...too much slow moving traffic this morning.

Bikers have a saying, well they have many some not for here. But, "never ride faster than your angle can fly". Sounds like yours is about 70mph....thats why they did not come back...
