I have a 04 9-5 Arc 2.3T sedan 188K. I have noticed since I have gotten the car almost 2 years ago that when I am cruising and then let off the gas to decelerate a weird noise coming from the front right wheel. I do not know how to describe the sound other than almost windmill like. Does anyone have any idea what it could be? It has been serviced on the wheels twice in the last 6 months and they did not find anything. The car rides smooth other than that sound which is more annoying than anything. Well, I hope nothing more serious.
