Done! It took longer than I expected, but I did it all without the benefit of power tools. In the pictures you can see the failed ball joint and the new one I replaced it with. I used the Jeep to drive back to the auto parts store to return the tools I rented to make sure everything is in order.
@kyle Nice job! Has to be a bit cool to drive the non-power tools you used back to where you got them in the car you fixed with them ;)
(I finally got the The Best of Hack and / sysadmin book by the way :) I like it!)
