Is there any way of lubricate a squeeking vibrator component?

The vibrator component in my old iPhone 4 is nowadays squeeking in a heartbreaking fashion, much similar as to a howling fan belt in an old car. I know you may replace the whole vibrator component all in all, but this sounds like a matter of lubrication! Isn't there a way to just lubricate with the right sort and amount of lubrication on the right spot and see if that does the trick? Meaning that I actually don't know neither the right amount, nor the spot or the type of lubrication... Just a though.
