| | | | Joined: Sep 2015 Posts: 12 New Guy | | New Guy Joined: Sep 2015 Posts: 12 | 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. | | | | | Joined: Jun 2004 Posts: 8,597 Riding in the Passing Lane | | Riding in the Passing Lane Joined: Jun 2004 Posts: 8,597 | Yes. There is a seal in the hub. You need to pull the hub/drum off to replace it. Read up on pulling the hub. There has been plenty of talk on this website about it. Do a search. Find repair manual & read up. This is not for the faint of heart. If not done right severe damage to the axle & hub will result.

Not too bad.
