As Hillrider says they vary. On some, like Campy, the freehub body is a separate part supported on it's own bearings and connected to the hub only by the ratchet mechanism which should be oiled periodically. Others, like Shimano attach the self-contained freehub module directly to the hub shell and support the entire assembly on a single pair of bearings.
Your best bet is to identify your hub, and go to the manufacturers website for a schematic view, and/or maintenance guide.
As a general rule, the freewheel ratchet mechanism gets a sticky oil film which won't build up and interfere with it's light action, while the ball bearings get greased.
