Help keep lubricant in and road grime out of your rear axle with the SKF differential pinion seal, part number 18833. This rear differential pinion seal is a direct-fit replacement for the listed applications. Those include the 1957-1979 Ford Thunderbird, 1965-1973 Ford Mustang, 1966-1983 Ford Bronco, 1966-1979 Lincoln Continental and 1975-1983 Ford F-150. See the "Vehicles it fits" section for the full list of vehicles and engine details.
The pinion seal stays stationary in the differential housing while its lip rides on the rotating pinion yoke. It seals the point where the driveshaft input enters the rear axle. A worn pinion seal may be the cause if you notice any of these signs: lubricant seeping near the yoke, oily residue on the housing, or a dropping differential fluid level.
SKF has developed seals since it invented the first integrated shaft seal in 1928. Its seals are made to specific designs using premium materials, chosen to suit both the application and its environment.
