Those bolts are definitely worth checking. The lower bolt on mine had loosened up enough to fall out. This resulted in enough looseness to let the bracket break. During a rainy week. Rugrat decided to let the wipers keep going despite them having "spazzed out". The (sharp) end of the broken bracket was thrashing around in the wiring and cut up the insulation a bit. Thank goodness for the heavy cloth tape around the wiring bundle, it kept the damage to a minimum.
