Stuck Lower control arm ball joints

currently trying to press out my ball joints. I've let it set for a night covered in rust penetration. but still nothing would love some advise.

 

Are you referring to the piece that attaches to the spindle? Or the ball joint being in the control are stuck?

I separate the piece from ball joint to spindle with a pickle fork with great success.

The ball joint in the control arm, remove the snap ring. Then it’s pressed in there super tight. I’ve done it with a ball joint press tool, and it’s a bitch. Now I use my shop press, and it takes a lot to get it to move initially. You could apply heat to the LCA where the ball joint goes in at. You’ll need either Mapp gas or oxy/acetylene. Propane isn’t hot enough.
