Detailed Description

FAG SS5595 is engineered to meet vehicle manufacturer specifications for sealing performance in demanding driveline environments. The metal-reinforced construction, spring tension, and auxiliary lip help maintain a consistent seal at the pinion area, while the polyacrylate material is selected for durability in service. This seal is a direct-fit choice for front axle applications on 2004-2012 Chevrolet Colorado, 2004-2012 GMC Canyon, 2006-2010 Hummer H3, 2009-2010 Hummer H3T, 2007-2008 Isuzu i-370, and 2006 Isuzu i-350.

What It Helps Address

• Gear oil leakage at the front differential pinion
• Contamination from dirt, dust, and moisture entering the seal area
• Premature wear caused by loss of lubricant at the driveline end
• Seal deterioration in high-demand front axle service
• Fitment issues when replacing an OE-style pinion seal on listed vehicles

Installation Notes and Tips

Verify the bore diameter, outside diameter, and seal width before installation to confirm proper fit. Inspect the pinion surface and surrounding housing for wear, scoring, or contamination before pressing in the new seal. Clean the sealing area thoroughly and install the seal squarely to avoid distortion. For best results, match the application to the exact vehicle, year, and front position listed for Chevrolet Colorado, GMC Canyon, Hummer H3, Hummer H3T, Isuzu i-370, and Isuzu i-350.

Quality Assurance

FAG designs seals using high-quality materials and application-specific specifications to support consistent sealing performance in driveline service. SS5595 is built to the dimensional and material requirements listed above for the confirmed front differential pinion applications.
