A first bearing and an axial bearing are provided. The hub is rotatably supported in a cantilevered arrangement by the first bearing in the housing and coaxially surrounds the countershaft. The hub has a free cantilevered end and the axial bearing is disposed on the free cantilevered end, wherein the axial bearing axially supports the countershaft and has radial play relative to the countershaft.
