This part is listed under two names, taper bearing cone and differential pinion bearing. As a tapered roller bearing cone, it carries both radial and thrust loads and helps support the rotating pinion. The catalog lists it for the front inner, rear outer and rear inner positions, depending on the application.
A differential pinion bearing may need replacing if you notice a whine or howl that changes on acceleration or deceleration, a rumbling noise, or play at the pinion. Worn gears and other components can make similar noises, so diagnose the cause before replacing parts.
