Want to see if anyone can make any sense of this.... My ARB air line is unhooked at the bulkhead and the axle breather hole completely open so there’s zero pressure inside the axle housing. But when I drive, it’s forcing oil out of the copper air line at the bulkhead fitting.
What could there possibly be to create enough pressure to push oil up and out through the copper line? There should be nothing happening except oil splashing around inside.
Thanks much
