Just because it wont look OEM doesn't mean it wont work
Btw not to highjack you, but when you removed the longer front axle tube, was there just a single tabbed spacer under axle or is it a pair? I know there is a big washer but that one is by it self and falls off when you remove the tube from the housing, I was wondering about if its just 1 or 2 after removing the actual axle from the c clipped gear. I'm paranoid I might have lost one when I pulled it apart with the slide hammer as I only got 1 tabbed spacer from under it, and I saw a youtube vid with a guy that pulled 2 from under it but it was from a 2007 model. Thought I would ask since I remember you had fun with one of those. Thanks!
Ignore this I found it!! Glad you had done this before, now I know I wasn't going crazy, looks like they changed the design later on, I had to stalk your profile like a mad man to hunt the picture! Thanks.
