I was able to do as advised, worked out well, one thing that happened though was when I tried to change the spur I couldnt get the out drives off, I looked in the manual and it showed there to be a pin that secures the outdrive to the diff shaft, I couldnt see it at all, than I removed the 4 fasteners that secure the spur gear to the diff and ried to remove the sun gear, I didnt have any luck there so I reassembled the diff and went with the 48 tooth
