Technical Service Bulletin Not applicable. Service The noises from the wheel bearing can be transmitted via the steering into the vehicle interior. Because of the close proximity, it can be difficult to distinguish them from rolling noises. Therefore, with such noises, check whether the wheel bearings of the front axle may be the source and replace the affected component. The following steps are helpful: 1. Does the frequency issue rise as the speed increases or does the sound get higher? 2. Does the noise get louder when steering? 3. Is the noise still present when slowing down? 4. Is the noise amplified on the steering wheel/airbag well? 5. Can the vibrations be felt on the unpressed coil spring when the wheel is turning? 6. When swapping around the wheel bearings, does the noise move with a particular bearing? Tip: Please precisely locate the source of the noise with acoustic testers. It is possible that a noise perceived on the left side of vehicle is caused by the right wheel bearing. The front wheel bearings should not be replaced in pairs. If the cause of the noise cannot be traced to a wheel bearing, continue the analysis on other components.
