Someone who's done this recently will hopefully chime in. My recall when I put new knuckles on my '98 is that the ball joints will press in from the underside and be retained by both the press fit as well as a snap ring to ensure the ball joint won't just fall out.

To remove the ball joint, you'd remove the dust boot, then the snap ring and press out from the domed side.

In both situations, the halfshaft will need to be removed from the knuckle/hub, and it would be easier to work with if the knuckle were removed from the vehicle.
