For a year i've had this stupid noise coming from the underneath or my truck. It sounds like a dry leaf is under my feet chattering around in the wind but i cant find anything that would be doin it. Now its coming from the other side floor and its making me crazy.

Has anyone had this noise? Its only around 40mph, and i know its nothing mechanical. thanks

 

best guess would be cat converter heat shield, orrr the heat pad thats stuck to your floor board is ripped...?

 

thanks for the response, theres no heat sheilds on my cats. its the strangest thing! its more annoying than an exhaust leak. SOMEDAY i'll figure it out

 

on my truck theres a heat wrap on the underside of the floor board..? possibility
