Help keep differential lubricant in and dirt and water out with the SKF Differential Pinion Seal 20459, a front-position seal that closes off the opening where the pinion shaft enters the differential housing. It fits many vehicles, among them the 2006-2008 Dodge Ram 1500, 2011-2020 Ram 2500 and 2003-2010 Dodge Ram 2500, and is a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list and engine details.
SKF invented the first integrated shaft seal in 1928 and has kept developing new seal designs and bonding techniques since then. Each SKF seal follows a specific design and uses premium materials chosen for its application and operating environment.
Signs this seal may need replacing include lubricant seeping around the pinion yoke or flange at the front differential, or a differential fluid level that keeps dropping. Find the source of the leak before you replace the seal.

This part cross-references / interchanges with the following part numbers:
Is this the right pinion seal for a Dodge Ram 1500?
It is listed as a direct-fit front-position replacement for the 2006-2008 Dodge Ram 1500. The Buyer's Guide tab shows every listed application.
What does a differential pinion seal do?
It seals the opening where the pinion shaft enters the differential housing. The seal body stays stationary while its lip contacts the rotating shaft, which helps keep lubricant in and dirt and water out.
What is the SKF 20459 made of?
The case is made from deep drawn sheet steel, which forms a rigid, stress-resistant body. The garter spring is made from cold drawn steel wire for fluid retention.
What are the signs of a leaking pinion seal?
Lubricant seeping around the pinion yoke or flange at the front differential, or a differential fluid level that keeps dropping, may mean the seal needs replacing. Find the source of the leak first.
What should I know before installing it?
Follow the vehicle service information for removing the pinion yoke or flange and for the nut torque and preload procedure. Then refill the differential with the specified lubricant.
