Hello guys, maybe someone can help me here. For months I have had the following problem with my Audi C4 2.8 E front drive: At speeds from about 130 km/h there are vibrations, in my opinion from the right front axle. These are getting stronger and stronger with increasing speed. Partially so that the Navi flies out of the bracket. Strange, however, it is there, sometimes it is gone. I have already visited various workshops and the following has already been changed: Brake discs including rubber wheels balanced- Stabis new- gear bearings new- wheel bearings new- dome bearings and dampers, all without success. Now I have the assumption that it might be the drive shaft. Does anyone know about you? What else should it be, almost everything has been changed?
