a portion of the article reads, "................ if the driveshaft separates while the vehicle is in motion, there be a sudden loss of propulsion, which can increase the risk of a crash. It’s not clear if any crashes have been traced back to this issue."
I'll bet crashes are, indeed, directly associated with this "issue".
I had a driveshaft break on me before while going down the expressway. Other than smacking the shit out of the under carriage it’s no big deal. I just took the entire thing off, threw it in the bed of the truck, threw it in 4 wheel drive and limped my way home.
