Just got a 2012 Ram 1600 with 5.7 hemi and noticed some odd rattling or metal on metal sound when lightly accelerating, it also does it while in park lightly revving the engine?
Exhaust issue maybe? This is my first truck since 2005.
Would the torque converter make noise like this?

Have the same year. Mine has a rattle do to a heat shield being loose. Have someone in the truck try to recreate issue, while you're outside(maybe help pinpoint the issue a bit better)

It appears to be the serpentine belt, I spayed a little wd 40 on the inside of the belt and noise is gone. Have to order a new one and install it.
