      Hi Charles, glad to assist you! The hole in the Transfer Case Output Shaft Seal - Part No. 4333N is called water drain hole. You should align the water drain hole in the output shaft oil seal with the drain groove in the extension housing, then using seal driver J-37668 or its equivalent, install the seal.
