A bearing and shaft arrangement of an automobile vehicle electric drive unit includes a gearbox. A first electric motor within the gearbox is engaged with and axially rotates a first shaft within the gearbox. A second electric motor within the gearbox is engaged with and axially rotates a second shaft within the gearbox. A first roller bearing assembly supports the first shaft to a first structural member of the gearbox. A second roller bearing assembly supports the second shaft to the first structural member of the gearbox. A thrust bearing is positioned between the first roller bearing assembly and the second roller bearing assembly and directly contacts the first shaft and the second shaft in a drive mode and reacts a first axial load of the first shaft and a second axial load of the second shaft directed toward the first axial load.
