Rear upper ball joints
 

I am having trouble removing the old upper ball joint in my 02 sebring sedan. I have the bolt free but the ball joint wont come out. Any suggestions?

You need a special tool, a ball joint puller of the proper size and configuration to press the stud out of the hole. Once you have removed the upper control arm, you'll need access to a press to press the ball joint out of the arm. Lacking that, take it to an automotive machine shop and have them press it out for you. Then have them press in the new ball joint.

If you smack the side of the spindle where the ball joint goes through with a hammer and it will pop loose. Then it can be pressed out in place with a ball joint press (basically a heavy duty C-clamp) you can rent from your local parts store.
