A shaft assembly having: a first shaft with an inner facing surface having: an inner facing spline extending between spline ends; an inner facing projection, adjacent to one of the spline ends, extending to an inner facing projection surface; and an inner facing projection seat, adjacent to another of the spline ends; and a second shaft having an outer facing surface having: an outer facing spline extending between spline ends; an outer facing projection, adjacent to one of the spline ends of the outer facing spline, extending to an outer projection surface; and an outer facing projection seat, adjacent to another of the ends of the outer facing spline; the first shaft at least partially surrounds the second shaft; the inner facing projection surface is disposed against the outer facing projection seat; and the outer facing projection surface disposed against the inner facing projection seat.

Disconnect assembly

A disconnect assembly (10) is provided and includes a rotatably drivable input shaft (20) including a first clutch portion (25), a rotating element (30) including a second clutch portion (33), which is movable between a first position, in which the first and second clutch portions drivably register with each other, and a second position, in which the first and second clutch portions are displaced from each other and a disconnect bearing (50). The disconnect bearing is disposed at an inner diameter (250) of the first clutch portion and configured to radially and axially secure the input shaft relative to the rotating element with the second clutch portion disposed in the first or second position.
