A driveline component with a housing, a differential case in the housing that is rotatable about an axis, and a park lock mechanism with first, second and third lock elements. The first lock element is coupled to the differential case for common rotation about the axis and has a plurality of first face teeth. The second lock element is fixedly coupled to the housing and has a plurality of first radial teeth. The third lock element has an annular body, which is disposed about the axis, a plurality of second radial teeth, which are fixedly coupled to the annular body and matingly engaged to the first radial teeth, and a plurality of second face teeth that are fixedly coupled to the annular body. The third lock element is movable between first and second positions to selectively disengage and engage the first and second face teeth. |

1. A driveline component comprising:
a housing defining a cavity; a differential assembly disposed in the cavity, the differential assembly having a differential case that is rotatable about a differential axis; and a park lock mechanism having a first lock element, a second lock element and a third lock element, the first lock element being coupled to the differential case for common rotation about the differential axis, the first lock element having a plurality of first face teeth that are disposed circumferentially about the differential axis, the second lock element being fixedly coupled to the housing and having a plurality of first radial teeth that are disposed circumferentially about the differential axis, the third lock element having an annular body, a plurality of second radial teeth and a plurality of second face teeth, the annular body being disposed about the differential axis, the second face teeth being fixedly coupled to the annular body and disposed about the differential axis, the second radial teeth being fixedly coupled to the annular body and meshingly engaged with the first radial teeth such that the third lock element is movable between a first position, in which the second face teeth are spaced apart from the first face teeth, and a second position in which the second face teeth are engaged to the first face teeth to non-rotatably couple the differential case to the housing. |
