So my truck is a 2021 bighorn 6.4 Hemi and it has 2104 on the odometer. The last two weeks I’ve noticed the sound in the video. This happens after the truck is warmed up and it’s definitely coming from the lower end. My 2019 Scat pack did not do this. Strange thing is it goes away then comes back. It’s not there on start up only starts knocking after it’s warmed up then goes away later.
