Renew the outer running surface of a worn tapered roller bearing with the Timken Differential Pinion Race / Transfer Case Idler Shaft Race 02420, a tapered roller bearing cup cataloged for the front position. It is a direct-fit replacement for the listed applications: the 1961-1972 Chevrolet K20 Pickup, 1961-1963 GMC 2500 Series, 1967-1972 GMC K25/K2500 Pickup, 1968-1972 Chevrolet K20 Suburban and 1968-1972 GMC K25/K2500 Suburban. See the "Vehicles it fits" section for engine details.
This part is listed under both names, differential pinion race and transfer case idler shaft race. The cup is the outer race that the tapered rollers ride against, and it helps carry the load passing through the bearing.
Signs this race may need replacing include a whining or growling noise, roughness or excess play at the bearing, and pitting or wear on the race surface. Diagnose the cause before replacing any parts. This listing is the outer cup only, so pair it with a new matching cone.
