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

The replacement process of the rear transfer case output shaft seal requires shields to be eliminated first if they exist as well as subsequent removal of the rear propeller shaft. Start by taking off the rear output shaft seal before examining the bushing of the rear output shaft for any damage or wear. You can use the transfer case rear bushing remover and installer (J 45380) to remove the rear output shaft bushing by placing its finger section ahead of the bushing then attaching tools before loosening the bushing with a wrench. The tool called transfer case rear bushing remover and installer (J 45380) should be used for installing the new output shaft bushing through a process where the tool and bushing align with the case while using a hammer to perform the installation step until the drain hole on the rear output shaft seal boot faces downward. To complete the repair process, employ the seal installer (J 37668-A) to put in a fresh front output shaft seal and then install the rear propeller shaft before inspecting and adding more fluid when needed and replacing the transfer case shield if applicable.

How to replace the front output transfer case seal on GMC Sierra 1500?

Proper vehicle support and lift techniques enable changing the front output shaft seal. You must first remove the transfer case shield (if present) before taking out the front propeller shaft. The internal front output shaft seal consists of two pieces which include an inner force-fit component that mounts on the output shaft. A flat-tipped screwdriver should be used first to shift the inner seal race forward before using a small pry bar for complete removal from the front output shaft. A flat-tipped screwdriver or small pry bar should be inserted into the space between the outer race lip and the transfer case to remove the remaining output shaft seal portion. To install new seals users must connect the output shaft seal installer (J 43484) to driver handle (J 8092) before inserting the seal onto the installer. The seal installation requires both tools to be used for mounting onto the front output shaft. The front propeller shaft installation proceeds next and the fluid level requires inspection and appropriate fluid addition before replacement of the transfer case shield if present. Lastly, the vehicle needs to be lowered down.

Q: How to replace the rear output transfer case seal on GMC Yukon?
A:
The replacement process of the rear transfer case output shaft seal requires shields to be eliminated first if they exist as well as subsequent removal of the rear propeller shaft. Start by taking off the rear output shaft seal before examining the bushing of the rear output shaft for any damage or wear. You can use the transfer case rear bushing remover and installer (J 45380) to remove the rear output shaft bushing by placing its finger section ahead of the bushing then attaching tools before loosening the bushing with a wrench. The tool called transfer case rear bushing remover and installer (J 45380) should be used for installing the new output shaft bushing through a process where the tool and bushing align with the case while using a hammer to perform the installation step until the drain hole on the rear output shaft seal boot faces downward. To complete the repair process, employ the seal installer (J 37668-A) to put in a fresh front output shaft seal and then install the rear propeller shaft before inspecting and adding more fluid when needed and replacing the transfer case shield if applicable.

Q: How to replace the front output transfer case seal on GMC Sierra 1500?
A:
Proper vehicle support and lift techniques enable changing the front output shaft seal. You must first remove the transfer case shield (if present) before taking out the front propeller shaft. The internal front output shaft seal consists of two pieces which include an inner force-fit component that mounts on the output shaft. A flat-tipped screwdriver should be used first to shift the inner seal race forward before using a small pry bar for complete removal from the front output shaft. A flat-tipped screwdriver or small pry bar should be inserted into the space between the outer race lip and the transfer case to remove the remaining output shaft seal portion. To install new seals users must connect the output shaft seal installer (J 43484) to driver handle (J 8092) before inserting the seal onto the installer. The seal installation requires both tools to be used for mounting onto the front output shaft. The front propeller shaft installation proceeds next and the fluid level requires inspection and appropriate fluid addition before replacement of the transfer case shield if present. Lastly, the vehicle needs to be lowered down.
