Abstract:
An axle assembly having an axle assembly with first and second sumps for holding a lubricant. A rotating ring gear associated with a differential can rotate through the lubricant in the first sump to cause a portion of the lubricant to cling to the ring gear. A portion of the lubricant that has clung to the ring gear can be removed from the ring gear and transferred to the second sump. The lubricant in the second sump can be drained to lubricate teeth of a pinion that is in meshing engagement with the ring gear and/or to lubricate bearings that support the pinion. A related method is also provided.
