Hardware Wii Remote rumble stopped working!

[PrimeTime 84]

Well, the rumble of one of my Wii Remotes stopped working, perhaps something loose inside or something.

Does anyone know what exactly can be and how to fix?

I am grateful for the answers, and yes, I know about the Home Menu.

make sure you didnt just turn off the rumble in the wii wiimote settings. if it still doesnt work, mail it to nintendo and let them fix it.
