Groaning noise coming from under my truck

[Big550]

Does anyone have this groaning noise under thier truck. It gets loader as the truck heats up. I have 11500 miles and have not seen any indication of it needing a regen. I have added DEF three times. Does the regen make noise and could my truck be stuck in regen? Help!! The noise is making me nuts!!

We need to know more about your truck, what year, must be a 2011 or 2012,
is it a F-550? From what I know I would go back to the dealer with only 11500 miles.

No need to try and diagnose it yourself.........its under warranty, let the dealer look at it.

I took truck to the dealer and the service advisor looked at me
Like I had two heads. So I bought the fuel filter kit and change them out. Noise is gone! The F d c m was screaming before I replaced the filter. Any thoughts why this would
Happen at 11900 miles?
It's a 2011 F550 with a6.7
