This front axle seal ring is a lip-type seal that retains lubricant in the axle housing and excludes contaminants from entering the bearing cavity. It sits between the rotating axle shaft and the stationary housing, forming a dynamic seal at the shaft contact surface. A worn or hardened seal allows grease or oil to leak past the lip, which can lead to bearing starvation and eventual axle failure. Corteco manufactures this seal to match the original housing bore and shaft diameter, so the interference fit and lip pressure are consistent with the factory assembly. On installation, ensure the seal bore is clean and free of burrs, and drive the seal squarely into the housing to avoid lip damage.
