Okay, this is a little weird. I just bought a used 2008 JK Unlimited with a factory hard top. I noticed a whistling noise that sounds like a tea kettle going off, if I go any faster than about 25 MPH. Figured it was the hard top. But the other day, the weather was nice enough for me to take off the two front panels of the Freedom Top. I STILL hear the whistling noise. What's up with that? Could this be the windshield? Something else? I'm kinda stumped. Any ideas?
