The differential output seals are the seals located at the output shafts of a vehicle's differential. They usually seal the axle shafts against the differential and prevent fluid from leaking out of the differential as it operates. The seal that allows that yoke to move in and out while still keeping the transmission or transfer case fluid sealed inside. Replacing seals are important to preserving the transmission and overall longevity of your vehicle.
