The traction assembly includes a gear mechanically coupled to the axle. The gear includes (i) an outer peripheral surface having a plurality of sensor teeth defined therein, (ii) a first shoulder extending in a first lateral direction, and (iii) a second shoulder extending in a second direction. The traction assembly also includes a bearing assembly attached to the differential housing, wherein (i) the bearing assembly includes a first bearing member and a second bearing member, (ii) the gear is interposed between the first bearing member and the second bearing member, (iii) the first shoulder of the gear contacts a first journal surface of the first bearing member, and (iv) the second shoulder of the gear contacts a second journal surface of the second bearing member. The traction assembly further includes a sensor for detecting rotation of the gear relative to the differential housing and generating a sensor signal in response thereto.
