Abstract
A vehicle powertrain may include a differential assembly having a housing disposed partially in a lubrication reservoir. The differential assembly translates rotational motion of a pinion gear to a pair of axle shafts extending from the housing and permits different rotational speeds of the axle shafts. One or more components of the differential assembly, e.g., one or more side gears, may include a plurality of radial grooves configured to distribute a lubricant from the lubrication reservoir while the first side gear rotates.
