Lower ball joint stud STUCK

try taking two hammers and hitting the outside diameter at the same time it allways works

Yeah, I always use two hammers. I never use a pickle fork, and it comes apart easy. I'm right handed, so I hold one hammer against the one side with my left hand, and then smack the right side with the other hammer, hard. It pops apart quickly every time. Pickle forks are way too much work.
