arctic cat 454 cv question

this may be a stupid question but this is my first utility quad.I picked this quad up with it needing some work.Well the front left axle is separated from the hub.my question is would i need a half shaft assembly or just the outer cv joint kit?Its still connected at the front differential.i seen the micro fiche online and they show the complete assembly with both inner and outer cv joints,i dont think i need the whole enchilada,maybe a dumb question but my 400ex or 250r arent 4 wheel drive,just want to be sure before ordering the wrong part(s),so..half shaft assembly or just the outer cv joint?thanx:confused: thanx
