Detailed Description

This National differential pinion seal, part number 710476, is engineered for the front outer position on vehicles using the Chrysler C205F differential. It is specified for applications such as the Dodge Dakota, Dodge Ram 1500, Chrysler Aspen, Dodge Durango, Mitsubishi Raider, and Ram 1500 where the seal must match the shaft and housing dimensions closely to maintain proper differential sealing. National has supplied sealing solutions for decades, and this seal reflects that focus with a bi-directional lip profile and polyacrylate construction.

This part cross-references Bosch 17259 for the same application.

What It Helps Address

• Differential gear oil seepage at the pinion seal area
• Fluid loss around the front outer differential seal
• Contamination entering the differential through a worn seal
• Noise or driveline concerns caused by low differential fluid level
• Seal wear from age, heat, and repeated driveline movement

Installation Notes and Tips

Verify the axle configuration, ring gear size, and differential type before ordering. Confirm the shaft diameter, housing bore, and seal width against the removed part to ensure the National 710476 matches the application. Clean the sealing surface thoroughly and inspect the pinion area for wear or scoring before installation.
