• Noise or driveline issues caused by low lubricant level
• Seal wear from age, heat, and road exposure
• Service replacement on Ram rear axle maintenance

Installation Notes and Tips

Confirm axle type before ordering, since fitment varies by rear axle configuration. Verify the shaft diameter, outside diameter, and width against the original seal and inspect the pinion yoke and sealing surface for wear or scoring before installation. Clean the sealing area thoroughly and follow the vehicle service procedure for pinion seal replacement and torque settings.
