I'm very curious as well. Could be a rare QA issue, could be something overlooked - hard to tell.

1. What motor was attached to the VersaPlanetary?
2. When was the VersaPlanetary purchased?
3. What orientation was the motor/gearbox in?
4. What was attached to the output shaft and how was it attached?
5. What sort of shock/vibration loads was the gearbox experiencing?
6. Do you remember having to fidget with the snap ring when assembling the gearbox?

9 Versaplanetaries in 3 seasons, 2 with BB550's, 1 with BB775, 6 with BAG (including 1 in a non-standard axial-load)- 0 with problems. I don't remember doing anything special with them, except making sure to read all of the little notes in the instructions and also manually reverse-running them after assembly to make sure they were assembled correctly.
