I've never had one let loose, but the front shaft on my 79 was being held on by two loose bolts when I got it. I did once watch a treefrog cause the driveline on a lifted ford ranger to break loose at the trans yoke. Lucky for the ford owner it was at a dead stop as the DL had no hoop holding it from hitting the ground.
