Ok, I'm trying to help out a girl that had her ceiling fan come off/out of the ceiling.
Problem is, it's in a mobile home and it doesn't mount the way a regular ceiling fan does. It looks like there is an junction box that had the wire connections, and the junction box was held into the plywood above the sheetrock with screws. There is sheetrock for the ceiling, and then about a 3 inch gap, and then the plywood. i was thinking about using larger screws in the junction box, and maybe some Liquid Nails on the top of the junction box for added strength. Or would silicone be a better choice for sticking the junction box to the plywood?? |

Quoted:
We have a Do It Yourself Forum, but there is no "good/right" way to do this. The house is built like crap and had a crap job. 
For sure, gluing it up is not good. How about some kind of anchor? Or more screws? Very true- mobile home construction and especially plumbing is the worst crap I've ever seen. It borders on criminal at times. I'm trying to get this knocked out today, and the simple answer seems to be to go with larger screws. I thought adding the adhesive might give another 'layer' of protection against it coming out again- but I didn't know if the Liquid Nails was too 'rigid' fr the fan vibration- that's why I was thinking about the silicone. and there are no rafters- at least none that I see. It's sheetrock ceiling, and then plywood sheathing directly above it. (it's a vaulted ceiling, so there's not really any 'attic' space to speak of. |

Can you put something up there substantial to screw in to? Maybe a 2x6 or something? |
You might contact member "brickeye" as he knows everything and has done/experienced everything. If anyone can give good advice it will be him. Good luck. 
Oh, another guy is highly experienced in home construction––"Ctbuilder" is close but I will try to find his exact screen name. |
I though that the Title said "Attack a Ceiling Fan".  I had many strategies for THAT.
You MUST attach a piece of wood between the studs and mount the fan to it. They make decorative pieces that are square and can do this job. You don't want that thing to fall, hitting someone, or rip out the wiring and start a fire. ANCHOR that bad boy. |

You can't make a cathedral ceiling with plywood alone. |

It is a mobile. OP needs to open up the ceiling and see what is in there. Of course that is where I would say, hire a licensed pro, so when your roof leaks or something, I am not on the hook for it.  |

Use bolts and nuts with big fender washers on the backside if you're going to attach the bracket/junction box onto plywood, at least.
All fans should have a bracket that the shaft slips into and hangs down from. You tilt the motor up at an angle to slip the shaft out of the bracket. If you balance the positioning of fan blades the best you can it shouldn't shake. |
