Installed thru left side, pull the clips from the fender, and the hex bolt, remove the inner fender, pull off the skid plate, loosen front diff and have some help to pull front diff forward while you pull the shaft out. you have to use three pieces off the old shaft, worst thing about mine was getting the boots on the drive shaft in place, make sure to slide the o rings towards the middle of the shaft /forums/images/graemlins/blush.gif, there is an anti rotation strap that is mounted to keep the unit from turning, my suggestion is to read the manual completely, then while installing it read 2 pages ahead during each step, would not hesitate to install another one, would definitely be easier the 2nd time around, and not having to work in the dark and in the dirt would have been a huge bonus too /forums/images/graemlins/frown.gif , but I couldn't wait.
