Rattling sound mostly in drive and stopped.

Noticing a fairly loud rattling when in drive, less so when I’m neutral. Seems to coming from around the middle of the truck I’d say under the cab? Any ideas? I opened the hood and put my hands on motor areas and ARB brackets and nothing it seems underneath more?! trucks a 2021 with barely 7000 miles.

 

Exhaust heat shield?

 

When you say in drive are you stopped with your foot on the brake or moving ?

 

UPDATE seems to be here where Exhaust passes through skids, there is no space.. if I pull on this it stops..

 

Throw a washer or two under that skid

 

Ya that’s a good idea.. I shouldnt need much, then clean it often.. surprised there isn’t much more room in the design from RCI

 

I had to notch and space my RCI to fit with my Y pipe

 

my solution to this was this! Worked!!

 

Yep. That’s about what I had to do as well.
