• Oil residue around the pinion yoke or driveshaft connection
• Seal wear caused by age, heat, or driveline movement
• Loss of lubrication at the front axle pinion interface

Installation Notes

Inspect the pinion yoke, sealing surface, and housing bore before installation. Clean the area thoroughly and verify the shaft diameter and seal dimensions match the application. For best results, install the seal squarely and confirm the front axle configuration matches the vehicle listing before reassembly.
