I saw this in the video I linked and it worked really slick. Super easy. At least with the right tools.
Use a large bearing splitter and you can just hand-tighten it to go between the bushing lip and the control arm.
then a metal cup of some sort on top. It took a surprisingly small amount of force so I'd guess even something like a piece of exhaust pipe (with a cap of some sort) would work fine.
I bought a cheap ball joint removal/installation tool and used the attachments.
you just push the arm off of the bushing.
he gets into it at :50

you need a press but as simple and cheap as they are and as useful as they turn out to be, not much reason not to have one if you have the room.
