In all my years of working on cars, I have never seen this happen. While driving away from the house, I heard a pop followed by a rattle over every bump. At first it sounded like the passenger door was not closed. Pretty soon after, I knew it was something in the suspension. When I got home, I pulled the wheel off and saw a broken spring! Has anyone ever seen anything like this before? The car only has 70k miles on it. I've heard of torsion bars breaking on 20+ year old 911s, but not on a relatively new car. It's under warranty, so I'm not worried about the expense, but I'm still scratching my head wondering how this could have happened. Anyone ever seen anything like this before?
