Earlier this year I had a similar issue on my 2011 Saab 9-5. I went through the same checks, trim, bearings etc.. and it turned out to be the tyres. In my case they were Michelin which looked perfect but when checked were actually warped. The noise sounded like a low hum at between 50 & 75mph. I replaced both rear tyres with Continentals and the problem was gone. Hope this helps.by ghostoftir - Main Forum
