Abstract
Vehicle steering differential have heretofore had a number of assembly, disassembly and serviceability disadvantages or have not been compact enough. The instant differential drive assembly overcomes these deficiencies by including a differential steering mechanism having first and second input gears and a plurality of cooperatively associated planetary gear elements driven thereby, and a mounting structure for rotatably supporting the input gears and the planetary gear elements along a central axis and for modularly positioning the differential steering mechanism in a protected location within the opening of a vehicle case. The mounting structure includes a one-piece carrier body defining a mounting face that is adapted to engage another mounting face of the case.
