This oil seal fits in the front axle housing, retaining lubricant and excluding contaminants at the shaft exit point. It sits between the rotating axle shaft and the stationary housing bore, maintaining a sealed boundary that prevents fluid loss and debris ingress. A worn seal allows lubricant to leak past the lip, which can lead to reduced lubrication in the hub assembly and accelerated bearing wear. Corteco manufactures this seal to match the original housing’s seal-groove geometry, so the lip contacts the shaft at the correct interference and angle without requiring shimming or adapter rings. On installation, ensure the seal is pressed squarely into the bore and that the shaft surface is free of burrs or scoring.
