What It Helps Address

• Differential oil seepage at the pinion seal area
• Fluid loss around the pinion shaft interface
• Contamination entering the differential housing through a worn seal
• Noise or driveline issues caused by improper sealing after service
• Leak repair during axle or differential maintenance

Installation Notes and Tips

Verify the axle designation, ring gear size, and front outer or rear outer position before installation. Inspect the pinion shaft and housing bore for wear, scoring, or debris, and replace the seal only after the sealing surfaces are clean and within specification. Match the seal dimensions to the application data for proper seating and retention.
