Description

Give your truck's differential a fresh outer bearing surface with the Timken Differential Race 34478, a tapered roller bearing cup cataloged for the rear right position. It is a direct-fit replacement for many Ford trucks, among them the 1987-1994 Ford CF8000, 1987-1994 Ford F-600 and 1987-1994 Ford F-700. See the "Vehicles it fits" section for the full list and engine details.

Tapered roller bearing specialist: Timken is recognized as a global leader in tapered roller bearings.
Built for demanding work: Engineered to deliver higher speeds, heavier loads and longer life.
Radial and axial capacity: Timken tapered roller bearing components can manage both radial and axial loads. They are engineered for durability in a compact space.
Replace as a set: Timken advises replacing the inner cone and the outer cup at the same time to maximize reliability and life.

The cup is the outer ring of a tapered roller bearing. The tapered rollers of the matching cone run against it, which helps support the differential under load. Signs a differential bearing may need replacing include a whine, growl or rumble from the differential that changes with road speed. Diagnose the cause before replacing parts. If a worn bearing is the cause, installing a new cup together with its matching cone addresses it.
