To get that ball joint out a serious hammer (literally like Thor's Hammer) is required.

and another hammer made of brass with a 2 ft handle to act as a drift held by another person while the first person swings the 10 lb sledge like an axe. It would take one swing to knock it out, two for rusty ones.

You can use a 4 lb sledge with more time (shoulder wear out)
