Gatorac:
When you Road Race with a live rear axle you must take preventative measures to keep the lubricant in the pumpkin. What happens is the
oil gets forced into the axle tubes in sweeping turns and the bearings (and gears) run dry. The cure are special seals that are fit into the axle tubes to prevent the
oil from being forced into the tubes by centrifical force. Circle Track racers know about this all to well.
