Please check notes in each part listing to ensure the Input Shaft Seal is correct for your 1984 JEEP GRAND WAGONEER with a 4.2L 258 engine. NATIONAL & SKF are competing brands, and each brand's Input Shaft Seal may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Input Shaft Seal fits only certain 1984 JEEP GRAND WAGONEER models.
Clicking a "More Info" link will display a picture and/or other details about that Input Shaft Seal in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Input Shaft Seal, click the "Add Part" button. Shipping costs will be shown on the Shopping Cart page. You may use your browser's Back button or click "Find More Parts" to find more Transfer Case parts, other JEEP GRAND WAGONEER parts or parts for a different vehicle. Please try our Interactive Catalog (click link above) for faster searching. Both catalogs use the same shopping cart so any auto parts you've already chosen for your 1984 JEEP will not be lost if you switch.
