With reference to Michael Morris's concerns over a rattle in front-end in his Holden Cruze (Carsguide 17/05/13) on rough roads I had the same problem with my car. My dealer replaced the top strut bush assemblies, which cured the problem and was covered under warranty.
Sounds like it could be a cure, but as you see from Alan Driscoll's e-mail on the same subject there could be more than one rattle and more than one cure.
