Cracked casting help

[CV2ram1500]

Can someone tell me which part this is please? I noticed the crack in the casting as I was changing my oil.

2017 ram 1500 5.7 with less than 30k miles.

I doubt that’s actually a crack. More likely casting flash. There’s been a few threads about this for the front diffs.
