My Jetta always make grinding when reach 60 to 70mph must be from gearbox or wheel bearing, I cant hear but I can feel the grinding, been like that for 3 years. Is it common? how to find and able to cure it!? Rob
Jack up the car and spin the wheels. You should be able to hear a rumble if a wheel bearings gone. You can also put your hand on the spring or suspension arm and feel roughness/vibration. Does the grinding go away with the clutch depressed? Sounds like a bearing to be honest.
i will try jack up car, I am sure it was gearbox bearing? Because noisy wheel bearing is a mot failure? Been griding like that for 3 years!
