Overview
The Crown Automotive 83504754 is a front outer transfer case output shaft oil seal for 1987–1990 Jeep Cherokee (XJ), Comanche and Wrangler (YJ) models. An oil seal in this position keeps transfer case lubricant from leaking past the output shaft, so it is the part to check when an XJ, Comanche or YJ shows fluid around that shaft.
The seal keeps transfer case lubricant from leaking past the output shaft in the front outer position. It is a direct fit replacement under part number 83504754.

Output seal wear and care
The front output seal is one of several seals that keep lubricant inside the transfer case, and it is exposed to road dirt and water at the same time. Leaks usually begin as a small weep around the shaft, then spread to the housing as the lip hardens. Catching them early keeps the rest of the drivetrain clean and reduces the chance of running the fluid low.
When the seal is replaced, the shaft surface should be inspected for grooves or rust before the new seal goes in. Support the vehicle on stands and drain the transfer case if the seal is dry or cracked. Fill with the correct fluid after the job and check the housing and seal area during the next few drives.
