What did you seal back the diff with? silicone?

I just used your basic black (oil resistant) gasket seal. In my experience virtually any quality sealant will work if you properly clean the surfaces. The oil is on the thick side, is not under pressure, and the diff housing is extremely rigid and won't flex at all - this would not typically be prone to leaking.
