How much ceiling fan wobble is acceptable?
Get/use a balancing kit.



An off balance fan shortens the life of the motor bearings, and if extreme, could pose risks if the mount is less than perfect. Also, a vibrating fan significantly shortens the life of attached light bulbs.

The kits allow you to experiment with a temporary weight (the U shaped slide) before mounting permanent balance weights. It is a trial and error process, but not overly difficult. 

You start with the temp weight very close to the motor and test each blade to see if it helps. If you find one that responds well, you then experiment with moving the temp weight further out until you find the sweet spot.

If the initial close placement does not show improvement on any blade, you repeat the process on each blade with the temp weight a bit further out.
