Detailed Description

This differential pinion race is used in rear inner bearing locations on 2007-2010 Ford F-350 Super Duty, 2007-2008 Ford E-250, and 2007-2008 Ford F-250 Super Duty applications with a 10.5 inch ring gear and automatic transmission output shaft bearing. Timken NP998236 is part of a tapered roller bearing system that supports both radial and axial loading in compact driveline packaging. For reliable service life, the inner cone and outer cup should be replaced together during bearing service.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems It Can Help Address

  • Noise from a worn rear differential pinion bearing race
  • Rough or inconsistent bearing surface contact
