Being that Moby has locking, I let it go longer than I should have but if oil can get out, water can get in and if we use him to do any wheeling this summer, water WILL be an issue.What a pain on the ass. That much fluid on the ground is a pretty decent axle seal leak though. How long was this going on before you repaired it?
And yes, changing out the seals with locking hubs is a really pain in the ass.
