The Meritor 1228F604 cup-bearing is a bearing cup, the outer race of a tapered roller bearing, and a genuine Meritor part from Pro Gear and Transmission. Our parts manual carries it three times in the Meritor MD-20-14X drive axle: as the outer pinion bearing cup in the Amboid tandem rear carrier and input components, and as the inner pinion bearing cup in the forward tandem main differential components and in the hypoid rear carrier and bearing cage components, one per assembly each time. The cup gives the rollers a hard, true surface to run on, so a worn one can show up as whine or grinding from the axle. Call us to confirm fit.
