Keep gear lubricant sealed inside the transfer case and dirt and moisture out with the National Transfer Case Output Shaft Seal 710660. This is the rear output shaft seal, dropping in as a direct-fit replacement across a wide range of trucks and SUVs, including the 2004-2007 Buick Rainier, 2002-2009 Chevrolet Trailblazer, 2001-2010 Dodge Dakota, 2001-2009 and 2011-2019 Dodge Durango, 2011-2019 Jeep Grand Cherokee, 2004-2019 Jeep Wrangler and 2005-2009 Saab 9-7X — see the Buyer's Guide tab for the complete application list.

  • Rear output shaft seal: installs at the transfer case rear output to retain fluid where the shaft exits the housing.
  • Stationary sealing lip: the seal body stays fixed in its bore while the lip rides against the rotating output shaft, holding lubricant in and contaminants out.
  • Direct-fit replacement: a one-per-application service seal for the listed vehicles.

A worn or hardened output shaft seal is a common source of fluid seepage at the rear of the transfer case. If a failed seal is the cause of your leak, replacing it with MPN 710660 restores the sealing surface. Inspect the shaft and mating bore during installation for the best result.
