A differential assembly with a case assembly, a plurality of first and second shoes, a plurality of first and second helical pinions, and first and second side gears. The case assembly defines first and second apertures and includes a case body and a case cap. The first and second shoes are integrally formed with the case body and the case cover, respectively. The first pinions are meshingly engaged to the first side gear and have pin portions that are received into the first apertures. The second pinions are meshingly engaged to the second side gear and have pin portions that are received into the second apertures. The first and second helical pinions frictionally engage an interior wall surface of the case body in response to a reaction force generated by meshing engagement with the first and second side gears, respectively, to limit differential motion between the first and second side gears.
