Put a large short socket or pipe under on a floor jack, under the control arm, that fits loose to the ball joint, jack up the jack, and hit the ball joint with a large hammer.

I just put the cup of the floor jack on the outer portion of the control arm and whale away. Lots of aggression required, so make sure your mad (not mad enough to swing outside the upper fender lip though).

Stop and look over the whole assembly. The threaded end of the ball joint will go down out of the spindle. If there is nothing holding it, the front coil spring will push the lower control arm down - the ball joint keeps the spring compressed. Make sure the spring cannot pop out. Once the ball joint comes apart, the lower control arm can swing down unless the jack under it is secure. If the shock is in place it should hold the spring in but I like to wrap a chain around the spring just to be sure it can't pop out.

Yes....be careful!! If that spring is not secure it can pop out...which is very dangerous!! To seperate the lower control arm from the spindle, you need to rent a "tuning fork", or spindle removal tool. It looks like a giant piano tuning fork, and the tynes go between the ball joint and the spindle, and when u hit the end of it, the spindle will seperate. The lower ball joint is pressed on, and you should be able to rent a tool for removing and installing. Google Chevelle Lower Ball Joint removal.....there are lots of sites and tips that will help....

I got it off the spindle so I assume im going to have to hammer it out through the bottom next. Will it be just as hard to get the new one it? Or would you advise buying a remover clamp thing.

How far in is the replacement supposed go? As tight as I can? I'm afraid of making it go unlevel and destroying the control arm
