QU50543 1-7/8" ID Output Seal for Ford NP205 Transfer Cases fits either the front or rear output of NP205 transfer cases in Ford trucks that have 1-7/8" output yoke hub diameters. Mostly used on Fords with QU50619 1310 series or QU40399 1330 series CV output yokes. Ford used as a single seal, but there is enough width in the bearing retainer to install 2 of these seals for maximum oil retention.
Lubricate the Seal Lip with clean grease or petroleum jelly before installing the yoke to provide initial lubrication.
The Ford NP205 seal retainers are deep enough for two seals. I like to run two of these seals for each yoke to minimize the chances of an oil leak.
