How to replace the rear output transfer case seal on GMC Sonoma?

The procedure to replace the rear transfer case output shaft seal begins with vehicle lifting and subsequent removal of the transfer case shield and then the rear propeller shaft. The procedure for changing one-piece rear propeller shafts needs proper attention while two-piece configuration replacements require similar steps. Check the rear output shaft bushing for damage after removing its seal before conducting an inspection. Use the transfer case rear bushing remover and installer (J45380) to perform the removal by placing finger sections before the bushing then attaching tube and forcing screw before wrench removal. Use j45380 to install a new rear output shaft bushing by applying the tool to the case position the bushing then insert it with a hammer. The drain hole on the boot of the rear output shaft seal should be oriented at the bottom position. The transfer case rear output shaft seal must first be installed by hand before use of the output shaft seal installer (J33843) completes the insertion process into the transfer case. Replace the rear propeller shaft before checking the transfer case fluid level and then reinstall the shield and lower the vehicle.
