Keep gear lubricant inside the rear axle and dirt and water out with the SKF differential pinion seal, part number 17190. This rear pinion seal is a direct-fit replacement for many vehicles, among them the 1967-1972 Chevrolet Camaro and 1963-1979 Chevrolet Corvette, along with many more Chevrolet, GMC, Buick and Oldsmobile applications. See the Buyer's Guide tab for the full list and engine details.
The seal sits in the differential housing where the pinion enters. Its body stays stationary while its lip contacts the rotating pinion assembly, which holds lubricant in and keeps contaminants out. SKF invented the first integrated shaft seal in 1928 and builds its seals to specific designs, using premium materials chosen for the application and its environment.
Signs this part may need replacing: Gear oil may seep or drip at the front of the rear differential where the driveshaft connects, or the pinion area may be wet and coated in grime. Confirm the source of the leak before replacing parts.
