How to replace the rear transfer case output shaft seal with a new transfer case seal on 2004 Chevrolet Trailblazer?

You need to start by jacking up the vehicle then removing its rear propeller shaft before proceeding. Inspection of the rear output shaft bushing should follow the removal of the rear output shaft seal. Check for any signs of scoring or wear during this step. Rephrase this procedure with the transfer case rear bushing remover and installer (J 45380). Begin by setting the finger section of this tool in front of the bushing then attach the tube and forcing screw to the finger section.

Reinstall the rear propeller shaft before checking the transfer case fluid level then lower the vehicle.
