Torque Arm Problem
did you tq the bolts to the proper tention or just yank the hell outa your ratchet and call it a day?
I think I read about this happening once a week with the Moser. Moser bolts need checked all the time, even with lock tight I would still check them.
If you read a few threads down or search there is both a broken BMR and Spohn torque arm from this happening.
