I have the exact same issue going on, but mine is loud and all the time. My mechanic tells me that my rear sway bar bushings are shot and so are my end links. The problem is, this car had the Aussie sway bar already installed when I bought it. I don't know where to find out what size/type of bushings/end links will fit on this type of sway bar. Not sure if Aussie makes different sizes or not. Any idea?
Thanks
