Auto Zone (Longmont, Colorado) rents the ball joint press ($106) and a pickle fork ($11), and returns those dollars when you return the tools which you can keep for 90 days. The ball joints are a heavy press in the knuckle, and the press makes the job fairly easy and safe. The press kit comes with three sleeves, but they may not be the correct size for your ball joints. I just did a similar ball joint job on an F-250 4WD, and it required some home made sleeves made from water pipe. It took a long cheater on the end of a 1/2 inch ratchet to press the old ball joints out of the knuckle. I was a bit surprised that the press did not bend. Be careful where you press on the new ball joints when you press them in; you can damage them otherwise. The instructions that come with the new joints explain this. Well, good luck.
