I bought a ball joint press for 100 bucks from princess auto up here (similar to harbour freight)
It worked on the one side of the ball joints and axle u joint that I did on my f 250, but it was a pain in the ***, because it didnt come with the ford specific parts of the kit. I would look for one with those ford specific parts (I dont know what they are in specific, but i have seen other kits with them)
