Matt,

The ball joint is held to the a-arm with three 19mm bolts and it is held to the bottom of the strut tube with four 12mm(?) bolts. Once it is removed from the car you will need to remove the part of the assembly that was bolted to the strut tube and attach it to the new ball joint. Removing it is a simple procedure of holding that part of the assembly in a vice and removing a nut (19mm?). However, when you attempt to attach that piece (the one that bolts to the bottom of the strut tube) to the ball joint you will find that it sometimes provides a challenge. It can be difficult to get the piece to "grasp" the ball joint enough to be tight enough to turn the nut without the piece slipping on the ball joint. I usually clean up the mating surfaces with lacquer thinner and tap the piece on (it is a tapered fit). It is a reverse of the removal in that you hold it in the vice by the piece that bolts to the bottom of the strut. When you apply torque to the nut there is no way to keep the threaded portion from turning other than the friction between the two pieces. This is much easier with an impact wrench. A series of quick pulls of the trigger seem to do the trick. Good luck.
