Tech Note 1: Before Installing
Lubricate the Seal Lip with clean grease or petroleum jelly before installing the yoke to provide initial lubrication.

Tech Note 2: Verify Size
Ford used output yokes with both 1-7/8" and 2-1/8" ground hub diameters. Verify what size seal you need BEFORE you place your order. The outside diameter is the same for both seal types. If you need 1-7/8" ID Seals, see QU50543.
