FAG SS3926 Differential Pinion Seal - Front

FAG SS3926 Differential Pinion Seal

The FAG SS3926 differential pinion seal is built for front axle service on select Ram 1500 and Dodge Ram 1500 applications. It uses a metal case, spring, and auxiliary lip design with Viton sealing material to help retain lubricant and keep contamination out of the differential pinion area.

Key Features

• Part number SS3926 for differential pinion seal replacement
• Metal, spring, and auxiliary lip seal type
• Viton sealing material for demanding driveline service
• 3.031 in bore diameter and 3.045 in outside diameter
• 1.693 in seal width for the specified axle application
• Fits 2011 Ram 1500, front, 8.00" ring gear
• Fits 2002-2010 Dodge Ram 1500, front, 8.00" ring gear

Detailed Description

FAG SS3926 is a differential pinion seal engineered for the front position on Ram 1500 and Dodge Ram 1500 models listed below. The seal dimensions, including the 76.987 mm bore diameter, 77.343 mm outside diameter, and 10.744 mm width, are matched to the specified 8.00" ring gear application. The Viton sealing material is selected for durability in driveline environments where heat, lubricant retention, and contamination control matter. This FAG SS3926 seal is a direct-fit style service part for the identified vehicles and axle configuration.

This part cross-references National 710836 and SKF 16993 for the same application.

What It Helps Address

• Differential gear oil leakage at the pinion seal area
• Contamination from dirt, dust, and moisture entering the axle housing
• Loss of lubricant around the front differential pinion
• Seal wear related to age, mileage, or driveline service conditions
• Noise or driveline concerns caused by low differential fluid levels

Installation Notes and Tips

Verify the axle configuration, ring gear size, and front position before ordering. Match the seal dimensions and OE reference numbers during service, and inspect the pinion yoke and sealing surface for wear or scoring before installation. Proper installation and correct lubrication are important for sealing performance on Ram 1500 and Dodge Ram 1500 front differential service.

Quality Assurance

FAG designs seals to meet vehicle manufacturer specifications and works with suppliers to maintain its quality standards. The SS3926 follows that approach with application-specific dimensions and Viton sealing material for the listed fitments.
