Styy, I had to do the very same thing, that is, press my rig's lower ball joints out on a 20 Ton Press. Harbor Freight tool didn't work for me either, in fact I broke one in the process. Couldn't get my ABS sensors out either. Like jdavis said, follow the abs sensor wire back about a foot and unplug it. Good luck, you'll get it, the shop press is the answer. It's also a good time to repack/replace your front wheel bearings and check/replace the inner wheel bearing seals while everything is apart.
