Abstract
A differential assembly includes a housing defining a space containing a volume of hydraulic fluid, the housing including interior surfaces. A gear that rotates in the housing includes surfaces that pass through the fluid as the gear rotates and on which the fluid is carried to the interior surfaces of the housing. A bearing located in the housing is supplied with fluid from a fluid path that hydraulically connects the interior surfaces and the bearing.
