Well, I am in the process of preparing to take out my transfer case and split it open to replace my rear output shaft bearing. I have looked everywhere for a video or good pics of what it takes to do. I am pretty mechanically inclined and think I can do this job. I just do not like any suprises that will stop my progress. I looked at various types of Chevy transfer case disassembly videos on youtube but can not find the NP149 disassembly at all. I knoe about the snap ring that holds on the rear half of the case and the snap ring in front of the output shaft bearing. What Iwould like to know is does the output shaft bearing have to be pressed on or off and if so what else is involved with removing the shaft from the case. If anyone has experience with this please let me know. Thanks for the help.
