I just got a glass shop to put some double sided tape under the side windshield mouldings, and it got rid of the terrible rattling noise I had as highway speeds. Got a 2007 NBS Silverado WITH a bug deflector. Oh, and before I got the deflector, I didnt have any problems with it

 

When I hit 70-75 mph, I start getting a whistling or high pitched noise on my '07 NBS crewcab. It sounds like it's coming from around the outside mirrors. Anyone else heard this?

 

Just for the record, I had to take my 07' new body style silverado in to the dealer for a leaky windsheild< they had to remove it and reseal it, the only noise I have had with the truck is the drivers side seatbelt harness, where it mounts to the door post, ( not a problem, if you use your belts) but Im old school!
