Abstract: An automotive propulsion system, a final drive assembly, and a bearing assembly are disclosed. The ball bearing assembly includes a bearing race structure having an inner race and an outer race, where the outer race is disposed concentrically about the inner race. A number of rotatable bearing elements (e.g., balls) are disposed between the inner race and the outer race. The bearing race structure has a plurality of threads extending therefrom (from either the outer race or the inner race). The bearing race structure is connected by the plurality of threads to an adjacent structure to prevent relative movement of the bearing race structure with respect to the adjacent structure.
