A torque arm mounting plate for a differential case housing a differential drive pinion gear. The mounting plate comprises an interface adapted to be circumjacently mounted about the differential drive pinion gear, and a torque arm bracket integral with the interface and spaced apart from the differential drive pinion gear. The torque arm bracket is adapted to fixedly engage one end of a torque arm. The torque arm mounting plate of the present invention provides a common interface between the torque arm and the differential carrier.
