Rear Axle Leak

I have a rear axle leak, it is leaking on the right hand side where the axle tube housing is pressed into the differential housing. This is the best way I can describe it with out drawing a picture. Is there any way to fix this? I will be going to a shop on Monday so any help this weekend would be appreciated. I am hoping that I do not have to get a new Axle.

Thanks,
Carnage
