Has anyone experienced a low frequency noise from their engine that is sort of random in pitch (but generally low-pitched) and varies slightly in volume?

It sounds like when an old car of mine had a bad bearing in the shaft that drives water pump. The shaft eventually snapped off when I was driving, stranding me.

The diagnosis from the dealer is that it might be the "pulley system".

Has anyone heard of this problem or of the noise that I'm describing (rather poorly I might add)?
