I have a 1949 Chevy 3800 and I have an issue with gear lube leaking out the driver side of the axle hub. When the wheel is on the fluid runs down and behind the wheel. As of right now I have the wheel and drum off the driver side. I don't know if there is a seal on that side of the axle that is bad and I need to replace or what. If anyone has any ideas or information about this, that would be really helpful.
