Final answer:
Oil-lubricated drive axle wheel bearings are lubricated by oil that is distributed from the banjo housing, which is designed to continuously circulate oil for lubrication.
Step-by-step explanation:
Oil-lubricated drive axle wheel bearings receive oil from the banjo housing.
The banjo housing is a component in the axle assembly that distributes oil to the bearings through channels or passages specifically designed for lubrication. Unlike grease-packed bearings, oil-lubricated bearings are part of a system that allows for continuous lubrication, often through the circulation of oil that flows back and forth between the components as they move.
