Check this out. Got this from another site, but apparently this brand spankin rebuilt ute was driving along when the tailshaft let go (well more than let go), and pierced the fuel tank causing a fire.

Terrible thing to have happen to ya. They had no insurance either. OUCH!

Has anyone ever seen a tailshaft twist like that? Looks like it failed spectacularly!! Would it have been the wrong size for the engine? Or a diff failure or something/ Looks pretty nasty..
