Abstract: A vehicle differential includes a housing, an input gear mounted to the housing so that the housing and input gear rotate together, a pinion shaft mounted in the housing, first and second pinion gears mounted on the pinion shaft, first and second side gears within the housing and engaged with the pinion gears, and a second gear mounted to the housing so that the second gear and the housing rotate together. Part of the second gear overlaps at least part of the pinion shaft and limits movement of the pinion shaft relative to the housing.

Abstract: In at least some implementations, a disconnect assembly for a power transfer unit includes a cam and a cam follower. The cam is driven for rotation and has a cam surface that is inclined relative to an axis of rotation and a void spaced from the cam surface. The cam follower has a cam engagement surface and is arranged to be engaged by the cam surface so that the cam follower is displaced axially during at least a portion of the rotation of the cam. One or both of the cam and the cam follower includes an interface surface provided at an angle to the axis of rotation to control axial movement of the cam follower during at least a portion of the rotation of the cam when the cam surface is not engaged with the cam engagement surface.

Abstract: A vehicle power transfer unit (PTU) disconnect assembly can include a first shaft, a second shaft, and a collar assembly. The first shaft has a first split-spline at its exterior surface. The second shaft is telescoped over the first shaft and has a set of splines at its exterior surface. A helical gear is carried by the second shaft. The collar assembly is situated around both of the first and second shafts. The collar assembly has a second split-spline at its interior surface.
