Keep the front differential's tapered roller bearing turning smoothly and quietly with the Timken Differential Race LM104911A. This bearing cup provides the precision race surface the tapered rollers ride against, and it installs as a direct-fit replacement for the listed front-differential applications: the 2000-2005 Ford Excursion, 1980-1999 Ford F-250, 1999-2005 Ford F-250 Super Duty, 1980-1997 Ford F-350, 1999-2004 Ford F-350 Super Duty, 1999-2004 Ford F-450 Super Duty, and 1999-2004 Ford F-550 Super Duty.
- Front differential position: serves as the race for the front differential's tapered roller bearing.
- Precision race surface: gives the tapered rollers a smooth, machined path to run on.
- Direct-fit component: replaces the worn race in the listed applications.
A bearing race and its matching roller bearing wear together, so if a worn race is behind a differential whine, howl, or roughness while rolling, this replaces it — inspect and replace the mating bearing at the same time for a complete repair. Signs the race may need replacing include gear-drive noise that changes with speed, pitting or scoring on the raceway, and play in the bearing.
Manufacturer part number LM104911A.
