I'm having someone replace my lower ball joint and he's having trouble separating the lower ball joint from the other piece after you loosen the 3 bolts. I know you can take a pry bar but it's not wanting to separate. Also I'm wondering how you could put the new one in without a shop press?
Do you
have the same problem?

Good morning,

The stud should have been released before removing the 3 bolts to the lower control arm.

I would have him put back the 3 bolts and separate the ball joint from the spindle first with a tuning fork or ball joint separator.
