Detailed Description

SKF 400500 is a differential pinion seal engineered for rear axle service on 2000-2002 Dodge Ram 2500 models in rear outer Dana 60 axle and Dana 70 axle configurations. The seal’s nitrile sealing surface is selected for axle sealing environments where lubricant retention and contamination control are critical. If you are servicing a Dodge Ram 2500 rear differential and need a pinion seal with the correct shaft and outside diameter dimensions, SKF 400500 provides the fit and sealing profile required for this application. This part cross-references 108048 and 946243 for the same application.

What It Helps Fix

• Differential gear oil seepage at the pinion area
• Contamination entering the axle housing through a worn seal
• Noise or wear concerns caused by low lubricant level
• Service issues during rear axle reseal work on Dodge Ram 2500 trucks
• Leakage around the pinion shaft on Dana 60 and Dana 70 axle setups

Installation Notes and Tips

Verify axle type, shaft diameter, and outside diameter before installation. Inspect the pinion yoke, sealing surface, and surrounding housing for wear or scoring before fitting the new seal. Clean the bore thoroughly and install the seal squarely to avoid distortion. For best results, confirm the application against the vehicle’s axle configuration before completing service on 2000-2002 Dodge Ram 2500 rear outer Dana 60 or Dana 70 assemblies.

Quality Assurance

SKF has a long history in seal design and development, including early integrated shaft seal innovation and continued refinement of bonding methods and materials. SKF 400500 is manufactured to support consistent sealing performance and long service life in axle applications.
