National 710996 Differential Pinion Seal - Rear Outer

National 710996 Differential Pinion Seal

The National 710996 differential pinion seal is a metric oil seal built for rear outer differential applications that demand precise sealing at the pinion shaft. It is a direct-fit option for many Mercedes-Benz, Chrysler, Dodge, and Jeep vehicles with a 215mm ring gear and ZF axle setup.

With an ethylene-acrylic sealing material and a counter-clockwise spiral lip design, this seal is engineered to help maintain proper lubricant retention at the pinion area. National has supported sealing applications for more than 75 years, and part number 710996 reflects that focus on dimensional accuracy and drivetrain sealing performance.

Key Features

Detailed Description

National 710996 is a differential pinion seal designed around metric sizing and OE-style fitment requirements. The seal measures 49.000 mm inside diameter, 80.200 mm outside diameter, and 11.000 mm thick, with a 3.386-inch flanged outside diameter and 3.150-inch housing bore. These dimensions matter when servicing the rear outer pinion area on vehicles such as Mercedes-Benz C63 AMG, E63 AMG S, and S550, as well as Chrysler 300, Dodge Charger, and Jeep Grand Cherokee applications listed below.

This seal is used in rear outer differential positions on vehicles equipped with a 215mm ring gear and ZF axle. It is a practical replacement choice when addressing pinion-area leakage on Mercedes-Benz CLS550, GL450, ML550, and related models. Part number 710996 is also associated with interchange references including SKF 19485A.

What This Seal Helps Address

• Differential oil seepage at the pinion shaft
• Fluid loss around the rear outer seal area
• Contamination entering the pinion seal interface
• Wear-related sealing issues during differential service
• Replacement needs on 215mm ring gear and ZF axle applications

Installation Notes and Tips

Verify shaft diameter, housing bore, and seal width before installation to confirm the correct fit. Inspect the pinion surface for grooves, corrosion, or scoring that could affect sealing performance. Clean the housing bore thoroughly and install the seal squarely to avoid lip distortion. Confirm the vehicle uses the rear outer position and the specified 215mm ring gear and ZF axle configuration before final assembly.

Quality Assurance

National has built its sealing product line over more than 75 years, with a focus on advanced sealing solutions for modern vehicles. The 710996 differential pinion seal is manufactured to support accurate fitment and dependable drivetrain sealing in the applications listed.
