Detailed Description

Timken NP912904 is a differential pinion race used in rear inner driveline locations where accurate bearing support is critical. Timken tapered roller bearing components are built for load handling in compact spaces, helping maintain stable pinion operation under both radial and axial forces. For reliable service life, the inner cone and outer cup should be replaced together during bearing service. This part is used in applications such as the 2011-2016 Ram 1500 rear inner, 2002-2008 Dodge Ram 1500 rear inner, and 2000-2010 Dodge Dakota rear inner.

What It Helps Address

  • Pinion bearing noise from worn race surfaces
  • Excessive driveline play at the rear differential
