If so, and it may get louder going around corners, it may the the wheel bearings. EdZ I have an ex groupe A M3, and a week ago I switched front pads with Ferodo racing because the old howled like crazy. But after a week the problem returns. The car is equipped with holed discs with ergal hub. Moreover the noise increases when the car is stopping. Another question, in Italy , where i live, the red 98 actanes fuel will be prohibited in few months. What about the unleaded fuel? Can it damages my car? The engine is very powerful (about 330 hp for 2,5 liters)and it has only 21000 kilometers! Do anyone of you know the seven speed X-trac gearbox?
