Auto diff is leaking. Options?

My diff is leaking from the right side axle and possibly the driveshaft.

Question: should I just grab one from the junker and refresh that and just drop it in? Or would you just pull yours and refresh that one? This isn't my only car so it's okay to go into a longer "service mode".

Next: Do I need to drop the entire carrier to do this if I keep my diff to refresh?

Lastly, I'm not quite ready for my manual swap, but I had planned on keeping the auto gearing diff, at least for now. Is it a bad idea to let it leak into the middle of the summer when I have to pull everything for the swap anyway? I'm putting less than 100 miles on the car a week.

Thanks
