I have a 2007 Chevy 4.8L Silverado Crew Cab Z71. When it was brand new it was super quite. As I began to put use and mileage into it I started to hear a creaking sound only when driving on the freeway. I took the truck back to the dealer 4 times and they claimed to have tighten up some nuts and screws. The noise was still there. I found out later it's was the windows at high speeds vibrate, Took it back to dealer and they told me the truck is not designed to go over 75MPH. Why does speedo read 120???? I cant go over 70 with the sound beginning. I have to crank up the radio to avoid hearing that annoying sound
