Timken Differential Pinion Race,Differential Race P/N:25523
Give your differential's tapered roller bearing a fresh outer running surface with the Timken Differential Race / Tapered Roller Bearing Cup 17831. This outer race (cup) fits many vehicles, including the 1986-2002 Nissan Maxima, 1965-1995 Toyota Land Cruiser and 1989-1997 Geo Tracker. See the "Vehicles it fits" section for the full vehicle list and engine details.
Timken describes this part as a tapered roller bearing cup, and it is listed here as a differential race, so it is known by both names. It is the outer ring that the tapered rollers ride against. The catalog lists it for both front and rear positions, depending on the application.
Signs a differential bearing may need replacing: a whine, growl or rumble from the differential that changes with vehicle speed. If a worn or damaged race is the cause, replacing this cup along with its matching cone addresses it. Diagnose the source of the noise before replacing parts.
