This noise emanates formt he frond end while the car is being driven over rough srufaces, although the surface by no means has to be too rough. It started out subtle, but has grown. I have a '05 SRX with 2k miles on it. Oddly enough when I brake over the rough road it goes away! Could a front brake caliper be loose? I am going to take it to the dealer at next chance, but any experience or advice with this problem would be helpful. Great driving car btw!
