2G "Arch" ball joint fail.

[Swanny]

Unlike the lateral control arm that has a ball joint fixed to it already when buying from an auto parts store, how should I got replacing this assembly? Is there just a ball joint that just needs to be pressed in, instead of buying the whole assembly?? This is the lower ball joint of the "arch", passenger side, and snapped today...I searched an only results I see are for the recall on the lateral control arms, more-than-likely I don't have the correct name for it.

Thanks
