How can I fix the noisy blower on my carrier central unit A/C, it makes a bibrating noise, I checked the motor, changed bushings, and still makes noise.

Check the squirel cage to make sure the hub did not break loose from the welds. Check to make sure it is center in the housing for the blower wheel (squirel cage), that it is not rubbing on either side. Check motor shaft is straight and not bent.
