Following up on this, basic tie rod end, in fact I guess it's stainless somehow but still has rust on it. Can't see behind the hose but there's a threaded nut on there that holds it on. Came right off and swapped it out for another $100 tie rod end made by teleflex.
oddly there really isn't much corrosion on anything in the engine bay this is the only piece. I wonder if some wires disconnected that would normally be connected to this to prevent this type of corrosion. Lots of green wires in the engine bay keeping everything connected
