In the middle of rebuilding the front suspension. have everything done cept lower balljoints and control arm bushings, well, i have the entire lower control arm unbolte and swung around, ez to get the bushings, but I cant figure out hoe to get the balljoint out? its about 1/4 of an inch below the cv axel and it has about an inch of threads left to come out, it just wants to back itself into the cv axel, am i supposed to grind and punch the rivits with the balljoint on the truck? thanks..
