I hate to say this but that kind of happened to me, I had a swivel on the rear springs on my zuk, it was attached to the spring perch. I was driving on a paved road going 40 mph (well under the speed limit) and my rear end locked up on me. Well I went a little sideways steered and then went the other ways sideways and when I was about 200 degrees into the turn my rear end dropped and then my sami pirouted ended up on my side, then it went on its nose again and I ended up on the other side and then I stopped. Skid marks were about 45 ft long but my sami was nearly 75 ft from where the skid marks stopped. Found the rear axle about 100 ft away with the wheels still on in a ditch. Not a fun time and I destroyed my sami.
