Solved.
I have found more and more, that if it is overly diffuse to find documentation or the answer to what something is, it’s likely because it’s wrong. So in the case, the bent up smaller metal ring is actually supposed to be nice and straight and large enough to be snap into the joint case, holding the bearing assembly from pulls out. Hence why mine did while removing the lca.
So there you go add this to a bored afternoon. Pull your cv boots off and check those snap rings.
