hmm... bad bearings causing the output to move up and down?
when you pulled the flange off did you try and move the output shaft up and down?
I've never seen that before! ![Confused :confused:](https://board.marlincrawler.com/Smileys/marlin/confused.gif)
i cant at all get the output to wiggle-i think it was a bad driveshaft/lack of cv that cause lots o vibrations/stress on the out put
