I have an Insinkerator disposal that
works well, however, it is very noisy.
It wasn't that way when it was new.
And, strangely, it sometimes (very
infrequently) get quiet. I've never
taken one of these apart. Is this something
that might be fixable?

Like JoeSpareBedroom, here's my .02 on the same subject in another
thread.

Do you ever clean it? Simple. Toss a tray or
two if ice cubes in it. Whenever I do this, after it's done and flushed
with water the only sound is the hum of the motor.

....and then again, it may just be f*ed up :-)
