Wind buffeting noise

Hey guys I noticed what sounds like wind buffeting noise (Like you're in a heavy cross wind/your windows are rolled down or door isn't closed noise) the other day on the freeway. At first I thought it was a one time thing but it happened again but I notice it only happens when I let off the throttle, if I give it acceleration it goes away and comes back as soon as I let off the gas. Only happens at freeway speeds but not constantly. Any ideas? Went underneath the truck for obvious signs of anything hanging loose etc

 

It does the same thing on my truck. I believe it is the door seals or the window seals. You should be able to pick up a set from a dealership or online somewhere. I've been meaning to do it, I'm just lazy.

 

Look for a write up on this in the forum
Some one used rubber tubing and slid in the oem rubber door moldings. Worked great!!!!

 

Ok I'm pretty sure I know the culprit. The back air vents (on the back of the cab) are loose. My truck got recently painted so the shop is ordering me a replacement
