It's easier just to pull the complete housing, really a simple job . Once out just follow RDs' instructions for mounting the speaker. When you go to put the housing back in remember that the tube on the housing will swivel up to 360* to make the reinstallation simple. There are only a few screws that hold the housing in. Lastly, it does help to also remove the blue chime module, I believe it just unplugs and has one screw for the mount.
