Detailed Description

FAG SS2938 is engineered as a transfer case output shaft seal for vehicles that rely on a sealed driveline to keep transfer case fluid where it belongs. The seal’s metal-and-spring construction, auxiliary lip, and polyacrylate sealing surface are specified for applications where dirt, dust, and moisture can shorten component life. This part number is listed for rear-position transfer case use on many popular trucks and SUVs, including Chevrolet Tahoe, GMC Yukon, and Chevrolet Silverado 1500 applications, along with additional fitments across GM, Ford, Dodge, Jeep, Cadillac, Lincoln, and Hummer platforms. FAG SS2938 is also referenced by global number 413 2938 100.

What It Helps Fix

• Transfer case fluid seepage at the output shaft
• Contamination entering the transfer case area
• Lubricant loss around the driveline seal surface
• Noise or wear related to low fluid level in the transfer case
• Seal deterioration from age, heat, and road exposure
