Rear End oil leaking from left side of axle TRX250ex

Just bought a 2006 250ex yesterday for $1k with a rear end leak.

Now at first I thought it would be as simple as pulling the wheel and hub off, and ramming an axle seal on there. Now I’m starting to think the axle area isn’t supposed to be filled with oil at all and the differential is actually leaking into the axle which is in turn leaking out.

I’m looking for advice, and guidance on how to do this. If anyone knows which parts I should buy, where I can download a service manual, that would be great to have as well. Thanks.
