What It Helps Address

  • Gear oil seepage at the differential pinion area

  • Seal wear from age, heat, and lubricant breakdown
  • Noise or driveline issues related to low axle lubricant level

Installation Notes

Verify shaft diameter, outside diameter, and width before installation to confirm the seal matches the axle housing and pinion surface. Clean the sealing bore and shaft surface thoroughly, and inspect for grooves or wear that could affect sealing performance. Use the correct lubricant during assembly and follow the vehicle service procedure for rear differential service.
