What It Helps Address

• Gear oil leakage at the differential pinion area
• Contamination from dirt, dust, and moisture
• Seal wear from age, heat, and driveline use
• Loss of lubricant that can affect axle component life
• Noise or service issues related to a worn pinion seal

Installation Notes and Tips

Verify axle configuration, ring gear size, and position before ordering, since this part is used across multiple rear and front applications. Inspect the pinion yoke and sealing surface for wear or grooves before installation, and replace any damaged mating surfaces as needed. Clean the housing bore thoroughly so the seal seats evenly and maintains proper alignment.
