This front axle seal ring is a radial shaft seal that retains lubricant inside the axle housing and excludes contaminants from entering the hub assembly. It sits at the interface between the rotating axle shaft and the stationary housing, where its sealing lip rides on the shaft surface. A worn or hardened seal allows grease or oil to leak past the lip, leading to reduced lubricant level in the final drive and eventual bearing or gear damage. Corteco manufactures this seal to the original geometry, matching the housing bore and shaft diameter so that the press fit and lip interference are correct without additional shimming or modification. On installation, ensure the seal bore is clean and free of burrs, and drive the seal square into the housing to avoid distorting the lip.
