Gang- when I put the rear windows half way down 40+mph there is a wind shaking noise and sunroof begins to rattle. Is there a fix for this , if so what can I check?

Thx

 

I had the same question when I got my 06 v70. Only when rear windows are down, right? Mine makes a deep buffeting sound, almost hurts my ears, like a vortex, strong enough to shake headliner. I know of no fix. If you crack the front windows it relieves the "pressure", sound goes away. I never put my rear windows down without the front.
