What It Helps Address

• Gear oil seepage at the differential pinion area
• Contamination entering the axle housing through a worn seal
• Leak-related lubricant loss around the pinion shaft
• Noise or wear concerns tied to low differential fluid level
• Service replacement for aged or hardened pinion seals

Installation Notes and Tips

• Confirm the shaft diameter, outside diameter, and width before installation.
• Inspect the pinion yoke and sealing surface for grooves or corrosion.
• Clean the housing bore and surrounding area before pressing in the new seal.
• Verify the seal orientation matches the differential design.
• Check differential fluid level after installation and road test for leaks.
