    Truck has 10k miles and is stock with the exception of a FM cat back. Noise goes away as soon as it warms up a little bit.

    Anyone ? Thanks!

    Where is the noise coming from? Engine? Exhaust?

    Sounds like a bad bearing on a pulley.

    I know this may sound dumb but I had a similar issue with 1K miles lol. I freaked out and I had my guy take a look at the truck, turned out to be some sort of plastic that broke kinda like a zip tie

    Remove the belts and spin the pulleys by hand. If its not a smooth spin, replace it. Or just replace them all. Start with the easy ones on the SC bracket.

    I agree remove the belts. It will at least rule out external vs internal sounds.
