take it down and start over. Most fans wobble because they are not properly supported by the bow they are attached to in the ceiling. First, the box it hangs from needs to be "fan rated". You can pick these up at the hardware/home improvement store....get the one for "remodel" work. It can be fit into your existing hole without too much effort. If the box is not flush with your ceiling when it is reinstalled you will need a round plaster ring to bring it flush with the surface(also available at hardeware store). This will give you a good solid box to re-attach to. The ticking sound is usually a wire nut or part of the wiring that is sticking into the fan housing. This can be addressed when you rehang the light. If it still wobbles you need to balance the blades. As you rotate your blades measure each one from the ceiling and see how far it hangs down. The one that is the lease distance from the ceiling usually needs a weight. You can weight it with a washer or coin and a piece of duct tape in the top of the blade. Turn it on again and see if this help, it's kind of a trial and error thing. If you don't like the location of the lights, you can get other light kits that you can use on your fan, or if you don't like the fan get a whole new one...they go on sale alot and don't cost that much, you might enjoy the new look.

You have to be careful with wiring something like this. You might be better off hiring an electrician just for the wiring part as they'll be able to utilize your existing wiring coming from your house and safely extend it out to the gazebo by running a line underground (using PVC) and bringing it up into your gazebo. They'll also be able to insulate any openings to make sure that the ceiling fan and any electrical connections are protected against any weather changes that happen during the year. You'll also want to have this on a switch rather than an outlet -- it's both more convenient and more attractive. (Consider adding a fan with lights so you can really get the most out of your summer evenings.) Ceiling fans are also quite heavy and even heavier while in motion, so you also need to be sure that the ceiling of your gazebo can handle the extra weight. Also, be sure that the blades clear the slope of the gazebo's roof. A job like this for most electricians (to just run the line) shouldn't run you more than $200.00 tops. (Especially if you're willing to dig the trench for the wire).
