NBRA321T is a differential rebuild kit from NTN BCA, supplied as a kit for differential service. A differential depends on its carrier bearings and pinion bearings to support the gears so each driven wheel can turn at its own speed, and noise is usually the first sign they are tiring: a rumble or whir at road speed that changes pitch in turns tends to point at the carrier bearings, while a whirr across a range of speeds tends to point at the pinion bearings. It is a genuine NTN BCA part sold by Pro Gear and Transmission. Call us to confirm proper fit for your application.
