This is the inner hub seal for the rear axle of a Dana 70 axle. This gets pressed into the hub/drum assembly and should be changed every time your rear hub/drum assembly is removed. As these seals age, they are what cause the liquid to leak out of your rear axle and drip down into your drum brakes. These seals are often nicked when the drum/hub assembly is serviced.
Two needed per axle (1 per hub).
This will fit 2WD and 4WD D350/W350 Trucks.
