Rear Differential Pinion Seal for Select Heavy-Duty Applications

FAG SS3251 is a rear differential pinion seal built for specific truck, van, and SUV applications that need reliable sealing at the axle pinion. With a Viton sealing material, metal construction, spring tension, and an auxiliary lip, this seal is designed to help maintain lubricant retention while keeping contamination out of the differential.

Use this seal when servicing rear axle leaks on vehicles such as the Jeep Liberty, Ford F-350 Super Duty, and Dodge Ram 2500. The FAG SS3251 part number is also referenced in OE-style service applications where precise dimensions matter.

Detailed Description

FAG SS3251 is engineered as a differential pinion seal for rear axle service where accurate fit and dependable sealing are critical. Its Viton sealing material is paired with a metal case, spring-loaded sealing edge, and auxiliary lip to help control gear oil leakage and reduce contamination at the pinion area. The listed dimensions support precise replacement selection for service work on compatible rear axle assemblies.

Compatible With rear applications on 2002-2007 Jeep Liberty, 1999-2005 Ford F-350 Super Duty, 2000-2002 Dodge Ram 2500, 2000-2002 Dodge Ram 3500, and additional rear axle platforms including Ford E-350, Chevrolet C3500, GMC K3500, and Dodge Ram 3500 service applications. The FAG SS3251 designation is also used in interchange references for related OE-style sealing needs.

What This Seal Helps Address

  • Rear differential pinion oil leakage
  • Contamination from dirt, dust, and moisture at the axle end
  • Loss of gear lubricant from worn or damaged seals
  • Service replacement for pinion seal wear during axle maintenance
  • Seal fitment needs on rear axle assemblies with matching dimensions

Installation Notes and Tips

Confirm axle configuration, seal dimensions, and application notes before installation. Clean the seal bore and pinion area thoroughly, inspect the shaft surface for wear or grooves, and verify that the replacement seal seats squarely during installation. For best results, match the rear axle application and gear ratio notes listed for the vehicle, especially on heavy-duty trucks and vans.

Quality Assurance

FAG designs sealing components to meet vehicle manufacturer specifications and works with suppliers to maintain its quality standards. This seal is built to support demanding wheel-end and axle sealing requirements in service applications where dimensional accuracy and material selection are important.
