Sounds like the bottom bearings ball dividers (race) may be broken allowing
the balls to shift inside the bearing, if so...DO NOT USE, can you move the
shaft sideways in any direction while rotating it by hand at any time? can
you feel any roughness when turning it by hand? does it rotate freely
backwards or feel like some resistance? If you answer yes to any of the
above being new return it to DeWalt service, do not run it like that as the
balls could seize & come to an abrupt stop causing much more damage.
Is there a chance that the shaft of your router bit is bent? with 1/2" shank
it is unlikely but not impossible either.
