Timken Differential Pinion Seal P/N:9316
National 9316 outer differential pinion seal for the 1994-2002 Dodge Ram 2500 and other vehicles seals the opening where the pinion shaft leaves the differential housing. It holds the differential fluid in and keeps dirt out.
Fluid weeping around the pinion shaft or an oily, damp differential housing can mean this seal is worn. A leaking cover gasket, a worn pinion bearing or a loose companion flange can be behind a leak too, so find the cause before you buy the seal.
It is listed for a wide range of Dodge, Chevrolet, Ford, GMC and International models, and it is a direct-fit replacement for the 1970-1985 Ford F-250 and the 1994-2002 Dodge Ram 3500. A 1970-1985 Ford F-250 takes one seal. If your vehicle is not named here, look up its year and model in the "Vehicles it fits" section.
