FAG SS2602 Differential Pinion Seal - Front or Rear

FAG SS2602 Differential Pinion Seal

The FAG SS2602 differential pinion seal is built for rear and front axle applications that need reliable sealing at the pinion area. With Viton sealing material and a multi-lip design, it helps keep gear oil contained while blocking dirt, dust, and moisture from entering the axle assembly.

Detailed Description

FAG SS2602 is a differential pinion seal for axle service where precise sealing dimensions matter. The Viton sealing material is selected for demanding drivetrain environments, while the rubber, spring, auxiliary lip, and inner shell construction supports consistent contact at the sealing surface. This makes the SS2602 a practical choice for Jeep TJ, Jeep Wrangler, and Jeep Grand Cherokee front axle service, as well as listed rear axle applications on Jeep TJ models.

This part cross-references Bosch 15525 and National 710461 for the same application. The SS2602 also aligns with catalog reference 4132602100.

What It Helps Address

• Gear oil seepage at the differential pinion area
• Contamination from dirt, dust, and moisture entering the axle
• Seal wear that can lead to fluid loss over time
• Noise or driveline concerns associated with low axle lubricant levels
• Service replacement needs on Jeep TJ, Jeep Wrangler, and Jeep Grand Cherokee axle assemblies

Installation Notes and Tips

Verify bore diameter, seal outside diameter, and seal width before installation to confirm the SS2602 matches the axle housing and pinion specification. Inspect the pinion yoke and sealing surface for grooves or damage, since a worn surface can shorten seal life. Clean the housing thoroughly before pressing in the new seal, and confirm the seal is seated squarely to avoid leaks after service.

Quality Assurance

FAG designs seals using high-quality materials and application-specific specifications to meet vehicle manufacturer requirements. The SS2602 follows that approach with a Viton sealing element and a multi-lip sealing structure for axle and driveline use.
