wheel seal ???

[busshawg]

I have replaced wheel bearings and wheel seal, how far should the test drive be before I would feel comforatble that this thing isn't going to leak. I messed up filling oil, I filled through the power divider plug which over filled it. On my first test run it pushed oil out the vent. I went home drained oil to the proper level , then took it on another 40 mile test run and all is dry. Is this far enough to feel comfortable that I didn't blow the seal??
