Abstract
An axle assembly including a differential carrier having a guide structure positioned in an upper portion of an interior face of the differential carrier. The guide structure includes a plurality of guides for directing the flow of lubricant during operation of the axle assembly. For example, the guide structure may include a plurality of guides, each guide having at least one surface on which to receive lubricant and direct flow of the received lubricant to at least one of a first feed opening and a second feed opening.
