According to the arb air locker instructions there needs to be vents at the axle tubes. I have the main vent at the top of the case but im assuming thats not enough. Where would the appropriate place to drill be?

The instructions should tell you where to drill. (They did on my 14bff) You only need the one vent, but you also need a way to get the airline out so you need to drill one hole for the line. I think I made mine right next to the vent so I could run the vent line and air line the same way.
just a question . but you do have new seals for the tubes/shafts ? I see you have the old ones out.
and yes leave the stock vent alone and just drill another hole aspr directions for the ARB line fitting hole.
also good time to remove the press in vent fitting and tap to a pipe thread and thread in a hose barb fitting . the stockers like to pop out after years of use .

here is my 60 with ARB hole drilled / tapped / fitting installed.
The arb directions seem very unclear on the vent drilling. I got the hd oil seals from ord that i need to put in. Sweetk30 do you have a picture of the vent hole placement for the axle tubes ? Thank you
in my pic you can see the factory slot on each side .
the ARB stuff looks like a general gide line to make sure you have the oil drain channels .
That guideline is for rear axles.
The problem they're trying to avoid is that oil (on a rear axle) will run down the axle tubes and not be able to return because ARB changes the shim system and by putting the shims outside the bearing, they dam up that oil path. So they're telling you to grind a drain so oil can return from the axle tubes and not run the differential dry.
On a front, you can ignore that because oil doesn't run down the tubes (on a non-CAD axle like you have, anyway).
