This was a major pain to do on my car. It was mostly getting the ball joint popped out of the control arm.

Tried everything. Had bought one of those fork things that slips through the ball joint to pop it out. I couldn't do it.

One of my neighbors saw me struggling and he came over with a big hammer and waked the fork a few times and it popped out.

I stuck a pick through the slot in the knuckle and tapped out the ball joint. I was fortunate in that mine was only slightly rusted.

Prying with a big screwdriver in the slot probably helps. It certainly did when reinstalling the new one. Not sure if covering the cup in the knuckle and the LBJ with antisieze made much difference on the install, but certainly counting on it making a difference a couple hundred K miles from now. Sure would have been nice if they had done this in the first place.

Mechanic's trick; don't bother with pickle forks. Saturate the connection between the ball joint and the arm with PB Blaster. Smack HARD with a large hammer (I use a 1.5lb mini-sledge / drilling hammer) 2-3 times and it will pop right out.

Professionals use an air-hammer which does more or less the same thing, but much quicker.

The biggest problem with that stinkin ball joint is the pinch bolt.. apply PB or whatever pen oil you have and HEAT it with a torch (OXY/ACL)... have watwr on hand to cool the wheel bearing once you breake the bolt loose..

So many people pop the head off that bolt its silly..

I have an old railroad spike, works great to open the pinch once you have the bolt OUT, the ball joint wont come out without it all the way out..
