Okay, most (sane) people insist on using a vise to remove and install the ball joints. I will show you how you can do this WITHOUT a vise. Be forewarned, you have to really muscle the ball joints in there with the help of some wisely-applied leverage. I don't own a vise so I had to do it this way, and frankly, I enjoyed the challenge. If you have access to a vice though, by all means, use it. First get your 1/2" drive breaker bar and the hydraulic jack handle and assume this position...
The trick is to hold the spindle end with your left hand and push downward while tightening the press with your right arm. Basically, you counter the weight. This is the right spindle. It is definitely more of a challenge to install the ball joints than to remove them. You really cannot do this without the breaker bar.
A view of the driver side spindle...
Voila!
