ABSTRACT:
A deflector for an axle housing to deflect circulated oil towards the oil galleries. Preferably, the deflector is formed as an indentation of a cover plate of the axle housing and is positioned adjacent the ring gear of a differential. When the ring gear rotates, oil is picked up from a reservoir and is directed toward the deflector. Oil is in turn deflected outwardly toward the oil galleries proximate the bearing caps to supply lubricating oil to the axle shafts and wheel end bearings. This arrangement has proved to eliminate wheel end bearing oil starvation at vehicle speeds as low as 24 mph.
