How to replace the rear output transfer case seal on Chevrolet Avalanche 1500?

The replacement process for the rear transfer case output shaft seal begins by removing both the transfer case shield when present along with the rear propeller shaft. Inspection of the rear output shaft bushing should take place after you discard the rear output shaft seal. Apply the j45380 transfer case rear bushing remover and installer to remove the rear output shaft bushing by inserting the finger section ahead of the bushing and following with tube and forcing screw attachment while pushing out the forcing screw before tightening the wrench to extract the bushing. The j45380 procedure for installing a new output shaft bushing requires users to follow installation of the bushing or finger section then attach the finger section to the main body of j45380 while positioning the tool and bushing against the case and using a hammer with j45380 to install the bushing with the boot drain hole directed downwards toward the ground. To install a new front output shaft seal you need to use the seal installer (J37668-A). Additionally install the rear propeller shaft and check the fluid level for possible addition of fluid before reinstalling the transfer case shield if equipped.
