FAG SS3349 Wheel Seal - Rear

Wheel Seal for Rear Axle Applications

The FAG SS3349 wheel seal is built for rear axle service on a wide range of Chevrolet and GMC trucks, SUVs, and commercial vehicles. It uses a nitrile sealing material with a metal, spring, and inner shell design to help keep wheel-end grease in place while blocking dirt, dust, and moisture.

For applications such as Chevrolet Silverado 3500, GMC Sierra 3500, and other rear axle platforms, this seal is specified to match demanding wheel-end requirements. The FAG SS3349 is engineered to support proper sealing performance where bearing protection and contamination control are critical.

Detailed Description

FAG SS3349 is a wheel seal engineered to meet vehicle manufacturer specifications for demanding driveline and axle service. Its nitrile sealing element is paired with a metal spring and inner shell structure to help maintain a consistent seal at the wheel end. This matters on heavy-duty and light-duty rear axle applications where grease retention and contamination exclusion directly affect bearing life.

Compatible With rear axle applications on 2001-2002 Chevrolet Silverado 3500, 2001-2002 GMC Sierra 3500, 1992-2000 Chevrolet C2500, 1991-2000 Chevrolet C3500, 1992-2000 Chevrolet K2500, 1991-2000 Chevrolet K3500, and related Chevrolet and GMC platforms listed in fitment. This part cross-references Gates 31870 for the same application.

What It Helps Solve

• Grease loss at the wheel end
• Dirt, dust, and moisture intrusion into the bearing area
• Premature wheel bearing wear from seal failure
• Leakage concerns on rear axle service
• Fitment issues when replacing an OE-style wheel seal on supported Chevrolet and GMC models

Installation Notes and Tips

Verify axle position, ring gear size, and seal dimensions before installation. This seal is listed for rear and rear inner positions depending on application, so confirm the exact vehicle configuration against the fitment data. Clean the seal bore and mating surfaces thoroughly, and inspect the bearing and hub components for wear before installing the new seal.
