if you share the same then I'm glad that I'm not the only one and the issue (if this is an issue at all) is not isolated.
Savarona or Clar, how about you guys? Are there no speedbumps or rough roads where you live?
My sound coming from the rear is definitely getting worse. Much more noticeable now and seemingly more frequent. I think I am at the point where I am going to have to do something about it. Did your service guys manage to work out what the cause of the sound was ?
