sedona axle

I am changing an axle on a 2005 kia sedona. It seems the axle is pressed in on the hub and Ill have to take the entire wheel assembly off. Photobucket is down and I didn't want to have to wait to post. https://www.facebook.com/photo.php?f...type=3&theater

I have 6 pictures. The first one is the lower ball joint. I can't seem to get this off. No amount of hammering seems to work. Should I take the entire control arm off? Or just the wheel assembly? I also have two pictures with a wrench on...something that connects to the control arm by some metal piece which curves up and is where my wrench is. What is the curved piece called and how do you get it off? The nuts simply spin and spin.

google alldatadiy it is around $29.95 for a years subscription.
They should have pictures but you will have to do some looking.

this might help
