    Drive an FJ60 without front axle?

    Hey all, I'm in the process of rebuilding the knuckles on my '85 FJ60. I've got everything apart right now, but while separating the birfield joint from the axle, the snap ring that keeps them together, well...snapped. I apparently didn't do enough research to know this was common so I...
