Does anyone else have a clicking noise coming from underneath? Spoke to the dealers service dept and they said it was caused by the expansion & contraction of the stainless steel exhaust. Its annoying when at a stop light and the windows are down and all you hear is this clicking.

 

Exhaust systems can cause a clicking sound, but ususlly only when they are cooling down. I would suggest you crawl under and listen, see if you can get a better what area of the truck this noise is coming from. When does it start?

It usually starts when warmed up. Its very noticeable when at a light and there're cars beside you because the sound bounces off. Not to mention embarrassing as well. Its not noticeable when all windows are up. But I'll crawl underneath to have a look/listen.
