In dramatic cases the crownwheel machines it's way out of the case.

If a pin does let go, they quite often blow a hole through the gbox.   :laugh:

Nooooooooooooo and be thankful!

More likely to be a bearing, bush or engine mount. Start of with a static check with the wheels off to find any unwanted 'play'.
