The first time I greased mine, it started throwing A LOT of grease all over the wheel, and I admit I panicked.
When you did the greasing, did you remove the sheet metal bearing cap? If not (it is hard to remove), then did you THOROUGHLY clean out all the old grease that piled up behind it as you injected the new grease? In my case, I had cleaned out some of the old grease, but not thoroughly. I believe what happened is that a bit more grease worked its way out as I was driving, and the bearing cap filled up and overflowed. Since then I have cleaned out the cap very thoroughly, and haven't had the "problem" again.
The thread linked below covers it. There used to be pictures, but they seem to be gone now. And the old YABB links don't work any more, of course.
