Keep differential lubricant where it belongs and road grime out with the SKF differential pinion seal, part number 18706. It is a direct-fit replacement for the 2000-2002 Dodge Ram 2500, and the catalog lists it for the front, rear, and rear inner positions on this application.
A pinion seal fits into the differential housing around the pinion shaft. The seal body stays stationary while its lip rides on the rotating pinion yoke or flange. This holds lubricant inside the axle and keeps contaminants out.
SKF invented the first integrated shaft seal in 1928 and has continued to develop new seal designs and bonding techniques since then. Its seals are built to specific designs with premium materials chosen to suit both the application and its operating environment.
Signs this part may need replacing include lubricant seeping around the pinion yoke, oily residue on the driveshaft end or the housing, and a dropping differential fluid level. Diagnose the source of the leak before you replace the seal. See the "Vehicles it fits" section for full application details.
