I just installed one in the front and the hardest part was getting the carrier to stay in the vise good(small vise)
. Also what worked best for me in getting the carrier out of the housing was using two pry bars on a upper and lower ring gear bolt, heres a picture of what Im talking about
. and put something soft under it or have someone ready to catch it just in case it falls out fast when you do that.
Here is a couple write-ups that I bookmarked:
and a fluid capacity chart:
I printed out the one from 4x4xplor when i did mine.
Also I can here the clicking sometimes when I turn slowly which isn't that bad but "they" say it goes away after a while. I'm testing it out tonight so I'll tell you how it does offroad.
hope that helps some...
