Help keep differential lubricant in and road grime out with the SKF differential pinion seal, part number 18928A. This front differential pinion seal is a direct-fit replacement for many vehicles, among them the 2008-2012 Nissan Pathfinder, 2005-2015 Nissan Armada and 2004-2015 Nissan Titan. See the "Vehicles it fits" section for the full list and engine-specific details.
The seal stays stationary, and its lip rides against the rotating pinion yoke or flange. It may need replacing if you see gear oil seeping where the driveshaft meets the front differential, an oily or dirt-caked housing, or a low differential fluid level. If a leaking pinion seal is causing these signs, this part replaces it.
SKF invented the first integrated shaft seal in 1928 and has kept developing new seal designs and bonding techniques since then. Each SKF seal is made to a specific design using premium materials suited to its application and operating environment. SKF seals have been in use on the road for more than a hundred years.
