for the bottom you dont need a press really, well kinda
what i did on my 99 was take a 2 jaw puller, put the arms around the LCA and pressed onto the ball joint.. make sure you put a thick piece of metal between then or you will just make a hole in the ball joint
then with the 'puller' still still pushingon the ball joint, i just took a big punch and a BFH and it came right out..
i think shops do that 1) bc i know atleast All Data says the whole LCA has to be replaced, and 2 because ford decided not to leave enough room to get the ball joint press between the ball joint and LCA
R.I.P. Dirty Debby. I miss that truck
New truck sports a chrome "C" on the fenders.
