Keep lubricant inside the rear differential and road grime out with the SKF Differential Pinion Seal, part number 23244. This rear pinion seal pairs a rigid steel case with a garter-spring-loaded sealing lip. It fits many vehicles, among them the 2006-2009 Dodge Ram 1500, 2011-2013 Ram 2500 and 1999-2009 Chevrolet Silverado 2500, and is a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for the full list and engine details.
The pinion seal sits where the pinion shaft exits the differential housing. Its body stays fixed in the housing while its sealing lip rides on the rotating pinion yoke or flange. This helps hold lubricant in and keep dirt and water away from the pinion bearings.
- Tested design and materials: SKF manufactures this seal with a quality-tested design and materials for correct fit.
- Cold drawn steel wire garter spring: the garter spring is made from cold drawn steel wire for fluid retention.
- Deep drawn sheet steel case: the body is formed from deep drawn sheet steel, giving it a rigid, stress-resistant metal case.
- Dirt and water protection: designed to guard against dirt and water getting past the seal.
SKF invented the first integrated shaft seal in 1928 and has kept pioneering new seal designs and bonding techniques since. It builds its seals to specific designs, using premium materials chosen for each application and its environment.
Signs a pinion seal may need replacing include lubricant seepage or wetness around the pinion yoke area and a low differential fluid level.

What does a differential pinion seal do?
It seals the opening where the pinion shaft exits the rear differential housing. This helps keep lubricant in and dirt and water out while the pinion yoke turns against its lip.
What is the SKF 23244 made of?
Its case is formed from deep drawn sheet steel for a rigid, stress-resistant body, and its garter spring uses cold drawn steel wire for fluid retention.
What are signs the pinion seal may need replacing?
Common signs include lubricant seepage or wetness around the pinion yoke area of the rear differential and a low differential fluid level. Find the source of the leak before replacing parts.
Is there anything to know before installing it?
Follow the vehicle's service procedure, including the pinion nut torque or preload specs. Check the service information on whether the nut and fasteners may be reused, and check the differential fluid level afterward.
