Detailed Description

Centric 417.67020 is a premium grease and oil seal for driveline and axle service. Its dimensions are specified for a precise sealing interface: 2.854-inch inside diameter, 0.740-inch width, and 4.246-inch outside diameter. In rear axle service, that fitment detail matters because the seal must maintain lubricant control while helping block road grit, moisture, and other contaminants.

This part is listed for 2003-2005 Dodge Ram 3500 rear inner, 2007-2010 Dodge Ram 3500 rear inner, and 2011-2018 Ram 3500 rear inner and rear applications with heavy duty dual rear wheels. If you are searching for a rear axle shaft seal for Ram 3500 dual rear wheel trucks, part number 417.67020 is the direct reference to use.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Installation Notes and Tips
