Differential, Service Gear Set
The Meritor Differential Gear Set is made for carrier service where the main gear pair controls how driveline force moves through the axle. The ring and pinion work together inside the differential, setting the power-transfer relationship before torque reaches the axle shafts. Gear work at this level depends on clean tooth contact, correct bearing setup, and careful carrier assembly. This kit keeps the repair focused on the core drive gears rather than wheel-end hardware, seals, or axle housing pieces. The Meritor B398961 places the matched gear set back into the differential’s main power section.
