You probably have th cv totally out of truck right? Bearing cover off (Allen head bolts) and c clip snap ring off, push cv through to inside?
Well the center shaft just pops into place. I took a hammer to the outer cage while having the smaller outer green cup clamped down and the shaft pops out. As far as getting the outer cage and balls out I don't know. Is there a retaining ring like the inner? I have never had problems with the outer. Have you thought about just getting a new generic one? Or finding a nice used one?
