Please check notes in each part listing to ensure the Pinion Bearing is correct for your 1981 BUICK RIVIERA with a 3.8L 231 Turbocharged engine. NATIONAL & SKF are competing brands, and each brand's Pinion Bearing may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Pinion Bearing fits only certain 1981 BUICK RIVIERA models.
Clicking a "More Info" link will display a picture and/or other details about that Pinion Bearing in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Pinion Bearing, 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 Transmission-Automatic parts, other BUICK RIVIERA 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 1981 BUICK will not be lost if you switch.
