Ever had the experience of breaking a rear axle, discovering it has broken in the diff meaning lots of hard work to replace it?
Recently I was working on the brakes on the C60S and when I was cleaning the axle prior to replacing it I found it had an interesting break - well it still worked but wouldn't have for much longer.
Have you seen one break like this before?
It looks like there might have been a fault with the steel. It still transmitted power of course but must have had a bit of spring in it!
