Common Issues This Seal Can Address

• Differential pinion seal leakage
• Contamination from dirt, moisture, and road debris
• Lubricant loss around the pinion area
• Wear related to compromised sealing surfaces
• Service replacement during driveline maintenance

Installation Notes and Tips

Verify the shaft diameter, housing bore, outside diameter, and width before installation. Clean the sealing surfaces thoroughly and inspect the pinion area for wear, scoring, or damage that could affect seal performance. Proper alignment during installation is important to achieve a secure seal and avoid premature leakage. Confirm the application by part number WS370199A and compare dimensions against the removed seal before final assembly.
