National Differential Pinion Bearing P/N:02872
Help support the pinion gear in your differential under load with the Timken Differential Pinion Bearing 02872, a tapered roller bearing cone built to manage both radial and axial loads. It is listed for many vehicle models, among them the 1994-2008 Dodge Ram 1500, 1975-1996 Ford F-150 and 1987-1995 Jeep Wrangler. See the Buyer's Guide tab for the full list and application details.
The catalog lists this cone for the front outer, rear outer and rear inner positions, depending on the application.
A whine or growl from the differential that changes between acceleration and coasting, or play at the pinion yoke, are signs a pinion bearing may need replacing. Diagnose the cause before ordering parts. If a worn pinion bearing is responsible, this cone replaces it. Pinion bearing service usually involves setting pinion depth and preload, so follow the vehicle service information during installation.
