D44 inner seal?

This may seem like a dumb question, but is there such thing as an inner axle seal on an XJ dana 44? I am putting an Aussie in and noticed that there seems to be space between the inner bearing and the tube itself just big enough for a seal. I have tried searching and have visited parts stores to check, but there seems to be no listing. Any info would be great, thanks.

Yeah, I know that space. No seal needed in there.

It needs to stay open for diff lube to reach the wheel bearings.

Yeah, I wasn't thinking when I posted this, but then I was like "duh, how do the outer bearing receive oil? Thanks though!
:doh:
