Upper ball joint removal

So the upper ball joint is just pressed into the upper arm? I can just take this off and bring it to my job and press it out?

Can you get just the balljoint? I know on the 1gs you are supposed to replace the whole control arm but you can still get the balljoint only, and in the 1gs it is pressed in.

yes you can just buy the balljoint, i think its just pressed in
