Check out this thread with a video of the transfer case reseal process:Some advice. There is some very tricky stuff during the rebuild process. Especially dealing with the variators, it is also a good idea to go with the pins instead of the balls in the variators. I ended up reusing the old variator piston seal rings since the replacements in the kit had horrible end laps that didn't want to seal very well at all. You will need a press to work on the variators. It is very easy during the install of the variator pistons to have them cock and do damage, like everything else bad design. Some videos show it as easy, nope. The forward and reverse clutches do not wear much. The transfer gear bearings are almost unobtainium you have to match them to similar bearings, that is if they are bad mine were. If it is out even the transfer case should be resealed, if it is similar to the 2004 model there is a very nasty internal seal that we made a special tool to install it, it requires a certain distance from the end of the shaft down in a so many inches or mm I forget the dimension.
