Here's the new input shaft installed in the transfer case. Even though the input shaft has a larger-diameter bore, it has the same outside diameter so it uses the same seal and bearing as the old input shaft. As long as this bearing isn't worn and there are no leaks, the swap only requires the new input shaft, some silicone, and fluid. However, if your transfer case needs a rebuild, now is a good time because the transfer case has to be completely disassembled to install the input shaft.
