I have a ceiling fan with a bent blade flange which has caused the fan to wobble. I was able to get replacement blade flanges but I'm not sure how to go about replacing it. The fan does not have a light fixture and the box which has the wiring for a light fixture somewhat obscures the screws for the blade flange. How would I go about getting to this part? Do I need to drop the fan or is there an easier way. Thanks.
