We have had far too many (factory installed, I think) snap rings fall out of ours over the past two years (not going to blame vex pro, we seem to like to put huge combined loads on the shafts), so we made plates that bolt on to the front of the gearbox and provide extra support for the shaft with a bearing. Haven't had any problems since and they're pretty easy to make with a cnc mil.
