Your just caught on the bottom now. Just need to pry it out with a long bar at the bottom. The bar comes in handy at times.
I would have left the top ball joint connected as you can see it's in the way now. Your spring compressor may be in the way as well. Also, take the sway bar off.
You need 2 spring compressors if you go that route (one for each side of the spring). If you can get into the middle of the spring you can use one. Air wrench works great for tightening up the spring.
I don't recommend that type of jack and also use 3 ton jack stands. A good trolley jack and stands are key to any job you take on with these cars.
You will be less concerned next time after you have seen these pop out without much drama.
I'm going to vid my next frame tear down.
