they are not that hard... i replaced my upper ball joints without changing the whole arm. if you do change the whole thing its a cake job, it would be 3 nuts, 2 for the arm and 1 for the ball joint. if you get the whole are do not cheap out and get them off ebay or something like that, but that should go without saying. i forget how i did mine it was a while ago i think i got them out with a big hammer or a press but im pretty sure i just pounded them out. just so you know though if you do replace just the ball joint the hole they sit in may become loose around the new ball joint, thats what happened to mine and we just worked back in with a hammer... if you dont really know what yer doing i would replace the whole thing
