I have a Hampton Bay Gossamer Windward II 54" ceiling fan. I am having trouble with wobble. I used a blade balance kit, but it really didn't help much. However, I was wondering if I am having trouble because it is a vaulted ceiling and the fan is about 12" from the ceiling at the low point and considerably more at the higher point. Does it cause a differential wind pressure on the fan if the ceiling is not level? Any help would be appreciated.

Thanks

It is entirely possible. You can try a longer downrod and see if it helps.
