What It Helps Address

• Rear differential gear oil seepage at the pinion area
• Contamination entering the axle housing through a worn seal
• Noise or wear concerns caused by low lubricant level
• Service replacement for damaged or hardened pinion seals
• Leak repair on 9.25-inch ring gear rear axle assemblies

Installation Notes and Tips

Inspect the pinion yoke, sealing surface, and surrounding axle components before installation. A worn or grooved shaft surface can shorten seal life, so the mating surface should be checked carefully during service. Confirm axle type and ring gear size before ordering, especially on Ram 1500, Dodge Dakota, and Dodge Durango applications.
