Hey folks. I've had my Bosch 4100 for a little over 6 months now, and it has begun to make a sort of... "loose", "rattly" or possibly "grinding" sound upon firing it up. It seems to go away after the first second or so, but it almost sounds like my DA polisher; kind of rough.
Is this a bearing? This soon?
I've found the replacement bearings, but I'm hesitant to use them if they're the problem. I'd rather get some completely sealed Japanese/American bearings and replace them all if that's the case. Unfortunately Bosch doesn't like to give out their sizes...
