National 711113 Transfer Case Input Shaft Seal - Right

Transfer Case Input Shaft Seal for GM AWD

National 711113 is a metric transfer case input shaft seal built for full-time 4WD applications that use Getrag 760 or Getrag 790 transfer cases. It is made with a fluoro-elastomer sealing material and a bi-directional lip design to help maintain a tight seal at the input shaft.

Use this seal when servicing the transfer case on vehicles such as the Buick Enclave, Chevrolet Equinox, Chevrolet Traverse, GMC Acadia, and GMC Terrain. National 711113 is also a direct-fit option for several Saturn and Pontiac models with the specified transfer case configuration.

What It Helps Fix

• Transfer case fluid seepage at the input shaft
• Oil residue around the transfer case housing
• Seal wear from age, heat, and drivetrain movement
• Loss of sealing integrity during transfer case service
• Noise or contamination concerns tied to low fluid level

Installation Notes and Tips

• Verify transfer case type before ordering: Getrag 760 or Getrag 790, as listed by application.
• Confirm shaft diameter, housing bore, and width against the removed seal.
• Inspect the input shaft surface for grooves or corrosion before installation.
• Clean the seal bore and surrounding housing thoroughly before pressing the new seal in place.
• Use proper installation tools to avoid distorting the lip or sealing edge.
