I think he's referring to the front drive shaft CV vs front axle CV's. I bought one for my Alpha last year and it came completely bone dry with no CV Grease in the box. Just the CV......
You have to tear open the old CV or in my case reach inside, release the clip holding the driveshaft to the CV, and then after you've greased your replacement slide it into place until it clicks and is once again locked into place by the internal clip.
I searched and searched for answers about the grease and finally just threw in some Lucas Red & Tacky II grease. Just about 10K on it now with zero issues.
