Ball joint questions

[Daytona#3895]

I was just going to do a front u-joint replacement on my 87 V-10. I removed everything and took the axle out. I noticed the knuckle had a lot of play and determined the ball joints need replacing. I could use a little clarification on the procedure. After removing the knuckle (its the driver side), I have to press the lower out first? Now when I go to press out the upper, do I have to remove the sleeve in order to remove the ball joint? Is there any certain place it must be set when installing the sleeve? Any and all help will be greatly appreciated. A small project just turned into a big one.....
