Diagnosing and locating the source of a noise over the internet is as difficult as emailing a piece of Mom's apple pie.. No matter how hard you try, you just can't do it.. All the posters have great intentions but they're just guessing. Nothing has been accomplished.. The worst thing you can do is throw some parts at it and hope "something sticks".. I suggest you take your truck to an experienced shop/mechanic and have them listen to it.. Then you'll know for sure..

I agree, but sometimes you get lucky and have someone who has went through the same exact issues and has a fix or an idea... right now i'm leaning towards driveline angles... that's my next area i need to familiarize myself with...
