Help - Grease able Pivot Shafts

Are those hardened? Pretty crazy snapping a 5/8" shaft like that unless it was hardened. The black look to them makes me think they went through a hardening process.

The stock ones are not hardened.

On the upside if there was a failure after the fact, the control arm has no where to go so your lca isn't going to fall off but I still wouldn't want those breaking off!
