Doesn't BMW say you can only change these bushings one time, then you need to replace the arm? Perhaps this is a result of trying to reuse an arm too many times?

Of course there are two other possibilities. Either a massive failure of the bushing, or it was put in by a mechanic who has absolutely no clue.
