Hi, I had also caught it now. At 49tkm whistles from the right back, diagnosis at the friendly : rear wheel bearings have said goodbye. There were replaced without discussion about warranty (XC90 Hat 2 1/2 years ) both bearings by an enhanced version, since Volvo seems to have installed in the first XC90 too weak bearings. But as long as you are replaced on warranty it is at least half as bad. Now is rest in the car again and I can pack confidently to 3 weeks vacation in southern France, of course with the XC90. Greeting Albert
