OK, you have the outer CV joint and the inner CV joint. We are talking about the inner CV joint here. Meaning, the joint closest to the differential. That joint is retained with a large C-clip on the inside of the "green cup" that the CV is in. It is covered by the INNER boot. You have to remove the inner boot band clamp, then pull the boot off the lip of the cup. Then, using a screwdriver or pick, you have to fish out the large C-clip. The joint will slide out of the "green cup". The "green cup" cannot be removed unless you drop the front axle. So no, we are not talking about the hub assembly. It sounds like you are past that part now.

Take a photo of where you are at and post it, this will help us see where you are at.
