Trying to replace my front drivers side axle shaft tonight before I leave for the weekend and it was going ok. However I can't get the inner piece out of the diff. Ive pulled pried and what have you for some time. I figuered id use the new outer with old inside but the aee different. HELP?

thanks. Jon
