Detailed Description

FAG SS2570 is engineered for rear transfer case sealing where shaft rotation and fluid retention demand a precise fit. The metal-backed construction, spring tension, and auxiliary lip work together to maintain contact at the sealing surface, while the polyacrylate material is selected for sealing durability in driveline environments. This part cross-references National 4583 for the same application.

Fitment includes rear applications such as 1993-2004 Jeep Grand Cherokee, 1991-1996 Jeep Cherokee, 1987-1989 Jeep Wrangler, 1996-2002 Chevrolet Camaro, 1996-2002 Pontiac Firebird, and 2004-2006 Pontiac GTO. It also covers rear transfer case service on Jeep CJ7, Scrambler, Comanche, Wagoneer, and Dakota/Durango applications listed in the fitment data. If you are replacing a rear transfer case output shaft seal on a Jeep Cherokee or Jeep Wrangler, SS2570 is a relevant OE-style service part to verify by application.

What This Seal Helps Address

• Transfer case fluid seepage at the output shaft
• Contamination from dirt, dust, and moisture entering the seal area
• Grease or lubricant loss around the driveline sealing surface
• Wear-related sealing issues on rear transfer case service
• Noise or driveline concerns caused by low fluid level from leakage

Installation Notes and Tips

Confirm bore diameter, seal outside diameter, and seal width before installation. Inspect the output shaft surface for grooves, corrosion, or damage that could affect sealing. Clean the housing thoroughly and install the seal squarely to avoid distortion. Verify rear transfer case application details, especially on Jeep Cherokee, Jeep Wrangler, and other models with multiple transfer case configurations.

Quality Assurance

FAG designs seals to meet vehicle manufacturer specifications and works with suppliers to maintain FAG quality standards. The SS2570 is built to the dimensional and material requirements needed for transfer case sealing service.
