National 711077 Differential Pinion Seal - Front Outer

National Differential Pinion Seal

The National 711077 differential pinion seal is built for sealing applications that demand precise dimensions and reliable fluid control. It uses a counter-clockwise spiral lip design and polyacrylate construction to help maintain sealing performance in driveline service.

Compatible with a range of Chrysler, Dodge, Mercedes-Benz, and Volkswagen applications, this seal is specified for vehicles using a 175mm ring gear and ZF axle where noted. The National 711077 is a direct-fit sealing component for differential service on applications such as the Chrysler 300 and Dodge Charger.

Key Features

• Counter-clockwise spiral lip design for controlled sealing action.
• Polyacrylate material for durability in sealing applications.
• Metric dimensions for accurate housing and shaft fitment.
• Designed as an oil seal for differential pinion service.
• National 711077 part number for easy identification and ordering.

Detailed Description

National 711077 is a differential pinion seal engineered around metric dimensions, including a 65.0 mm housing bore, 45.0 mm shaft size, and 9.0 mm width. Its 65.2 mm outside diameter supports precise installation in the specified housing, while the spiral lip profile helps manage lubricant retention in driveline sealing use. This part cross-references Chrysler, Dodge, and Mercedes-Benz applications, including OE-style numbers used for the same service position.

Fitment includes 2005-2012 Chrysler 300, front outer; 2007-2012 Dodge Charger, front outer; 2005-2008 Dodge Magnum, front outer; and multiple Mercedes-Benz applications such as E350, E550, C280, C350, E500, S430, S500, C240, C320, and E320. It also covers Volkswagen EuroVan applications listed for 1997 and 1999-2003. For buyers searching for a differential pinion seal for Chrysler 300, Dodge Charger, or Mercedes-Benz driveline service, the National 711077 provides a focused fitment match.

What It Is Used For

• Replacing a worn differential pinion seal that allows gear oil leakage.
• Restoring sealing at the pinion area after driveline service.
• Addressing seepage around the differential housing interface.
• Supporting proper lubricant retention in the axle assembly.
• Correcting seal wear related to age, heat, or contamination.

Installation Notes and Tips

Verify the axle configuration, ring gear size, and housing dimensions before installation. This seal is listed for front outer applications with 175mm ring gear and ZF axle notes on several vehicles, so match the service position exactly to the vehicle build. Clean the bore and shaft surface thoroughly before installing the seal to help achieve proper seating.

Quality Assurance

National has supplied sealing solutions for more than 75 years and is recognized for engineering focused on modern vehicle requirements. The 711077 reflects that sealing expertise in a metric, application-specific differential pinion seal.
