I have a loud rattle sound in the upper drivers side of my 2008 unlimited. I have driven other jeep unlimiteds and do not here that sound. It happens if the top is up or down. I have taken it in a couple of times and the jeep mechanic cannot figure out what is causing it. I'm sure it's the wind either going around something or threw something. If the top is down and I put my hand up over where the top front is, the sound goes away which makes me think it's something around the top of the window. Has anybody else experienced anything like this and how did you resolve it? the sound starts at about 40mph and stays pretty constent if you stay above that speed. Any suggestions or advice would greatly be appreciated. Thanks!
