This front axle gasket seals the joint between the axle housing and the final drive carrier. It prevents lubricant leakage from the axle assembly and keeps contaminants from entering the bearing cavity. A compromised gasket causes oil seepage at the split line, which can lead to reduced lubricant level and eventual bearing damage. This component is manufactured to the original profile, matching the sealing surface geometry of the housing so no additional sealant is required. On reinstallation, clean both mating surfaces thoroughly and tighten the housing bolts to the specified torque.
