I have a 04 wrx and swapping in a sti rear diff and axeles, first i couldnt "get the axeles to go into the diff they would go in about 2 " and that was it so i looked in, and the little o ring clip on the end of the axel stayed in there so i pryed that out, and then tryed pushing the axel back in and still no luck i tried for 3 hours messing around with it and i just cant get it to go in!! What am i missing out on doing???? Thanks!

anyone??/
