I have been following this for about 6 months when I first noticed my car was doing this...the one thing that I couldn't find was someone asking about the rear axle/cv joints. Doesn't this sound like something that could be produced by a bad cv joint? If you think about the circumstances that bring it up it could make sense: hard acceleration + worse when turning = the rear suspension getting more loaded and having those cv joints at larger angles under greater power. I looked under my car and found that when nothing is in the vehicle there is already a small angle in the cv joint - add weight in the rear and/or load the suspension with hard acceleration and that angle gets even larger...the only thing I cant explain is why it gets SO HORRIBLE when its below 30 degrees outside. Thought I would throw it out there and see what you guys think.
