That puts the bar into the most extreme twist condition it will ever see, and sends bracket loads through the roof. This can occur at high speeds, but it can even happen at low speeds, like during the body twist caused by a severely banked driveway.
Bottom line, it scares me to think that a welded plate let go...

Sounds right to me. My vertical mounts (hangers) broke while driving on ice ruts. Lot's of extreme twisting! Maybe this is all a combination of weak material in factory mounts, extreme loading, and bushings that are too tight, or under-lubed?
