I won't muddy this thread too much, since it's not my thread, but I'll say these two items.And by engineers, I am referring to engineers with an actual engineering degree picked from within the automotive industry. I understand your confusion since people through around the term engineer and engineering like it is nothing. I am talking about the real thing.
Regarding testing airflow and other details, when all of your gear is subjected to SAE testing, all critical details are tested. Who else subjects their systems to SAE testing besides AEV?
It might be the front driveshaft if you're still running the stock one. We had a rattling (almost grinding) noise when turning in 4wd with our 2022 Ram 3500 diesel as well. Also heard it occasionally when the suspension flexed enough in 4wd.I've been continuing to use and abuse this truck and loving it. 25,000 miles on the odo, 8,000 of those towing 10k plus. A good bit of offroad miles and so far no major issues. I have had the truck in once for a surging issue and they updated the TCM and now it's golden. The only thing I need to track down is a rattling bearing noise when turning in 4wd at low speeds. It's pretty much done it since I got it but is progressively getting worse.
This is in fact my issue as well. I was doing a good bit of research after my dealer told me its Carli's fault for having too gnarly of a driveline angle (it's not bad at all) and I came across a TSB that has the exact issue. I'm currently waiting on my dealer to review it and get back to me but sounds like I might be able to have the driveshaft replaced under warranty which will be awesome.It might be the front driveshaft if you're still running the stock one.

It started after our build which includes the 3.25" Carli Pintop and 37" tires. After a lot of testing/troubleshooting, it turned out to be the rzeppa joint on the transfer case side of the front driveshaft. Replacing it with a double cardan driveshaft solved the problem. Part of the troubleshooting included rotating the transfer case to reduce the angle of the driveshaft/differential connections. We did that before replacing the driveshaft, but with the stock shaft, it still rattled when turning in 4wd. We left the clocking kit on the transfer case with the new driveshaft for the improved driveline angles, but that mod might not have been needed.
The shop that did our work told me that they had seen (heard) the same problem on a number of other Rams, but they saw it more frequently on a couple combinations of model and year. Lifted 2022 3500s were definitely one of them whether it was a Carli or AEV lift. Sounded like some change in the rzeppa joint might have occurred (different part, bad run of parts, different supplier...).This is in fact my issue as well.

To be fair, the trans issue was due to a snap ring that affected only the Aisin and only for a few months of production. It's really sad for sure, but it's also a small blimp. I haven't heard of any specific engine issues with the 22s, although I know there have been issues with the hydraulic lifters because guys ignore the oil weight change either from ignorance or pride.It's sad to see so many issues with the transmissions and now the Cummins on the 2022+ HD's.

Oh, yeah. I'll fully admit that may be an issue, but the number of times that actually happens is so so so exceptionally small. That grid heater bolt thing has been discussed to death for a decade or more at this point.The Cummins issue is the grid heater bolt that fails and falls into the intake and eventually the cylinder.
I'm gonna rock my grid heater bolt till it takes out the block! Only way to go out is with a big bang. Hopefully it's at 3k rpm, on a 39% grade, with the 40's eating hard! 🤣🤣🤣
