Q:
How to replace the rear transfer case output shaft seal with a transfer case seal on Cadillac Escalade? Posted by Customer
A:
Before you replace the rear transfer case output shaft seal, raise the vehicle. If there are shields on the transfer case, take them off. After that, take out the rear propeller shaft. After that, disconnect the rear output shaft seal in the transmission. For the installation process, use the j29162 (Rear Output Shaft Seal Installer) and prior to installing, put a small amount of automatic transfer case oil gm p/n 12378396 on the seal's mating surface. After that, install the rear propeller shaft again. Examine the level of oil in the transfer case and place more as necessary. After that, fit the transfer case shields and then set the vehicle down on the ground.

Q:
How to replace the front output transfer case seal on Chevrolet K3500? Posted by Customer
A:
The replacement process of the front transfer case output shaft seal begins by raising the vehicle with additional steps directing the removal of transfer case shields when present. First remove the front propeller shaft together with the exhaust crossover pipe. Begin the front output shaft seal removal process by uninstalling the inner sleeve and then continuing to detach the outer part of the seal. Replacements for front output shaft seals necessitate the use of either j35870 front output shaft seal installer from production start through mid-1999 or j43484 front output shaft seal installer after mid-1999. A layer of dexron(R) iii oil from gm p/n 12346143 must lubricate both seal mating surfaces before the seal installation process. Place the seal in a straight position. Verify the installment of transfer case oil level before you may need to add extra oil. Reinstall the front propeller shaft as well as the exhaust crossover pipe and transfer case shields if equipped before lowering the vehicle.

Q:
How to replace the front output transfer case seal on GMC Savana 1500? Posted by Customer
A:
The first step to replace the front output shaft seal involves raising the vehicle along with front propeller shaft removal. The front output shaft seal includes two separate internal pieces where the inner segment tightly attaches to the front output shaft. The flat-tipped screwdriver should be used to slide the inner race forward before a pry bar can remove the seal's inner section. A flat-tipped screwdriver or small pry bar should be inserted between the Transfer Case and outer race of the seal to separate them before removing the outer part of the seal. The j 43484 (Front Output Shaft Seal Installer) along with the j 8092 (Universal Handle) should be used to mount the Transfer Case output seal before reinstalling the front propeller shaft. Users should check the Transfer Case fluid level followed by lowering their vehicle after installation.
