一辆2011款2.4L奥迪A6,行驶的时候有时向左跑偏,有时候向右。另外方向盘感觉有大概5mm左右的旷墨,请问是怎么回事?邵青:跑偏的故障有必要做四轮定位检查一下,观搴车轮外倾角还有前束这两个数据。因为四轮定位的数值如果不正确的话,便会出现跑偏时而向左时而向右的情况。5mm左右的自由间隙可能是车轮横拉杆的球头发生旷量以后,引起自由间隙偏大,或者是齿条式转向机的齿轮有轻微磨损,也会出现自由旷量。 A 2011 2.4L Audi A6, traveling sometimes left deviation, sometimes right. In addition the steering wheel feeling about about 5 mm Kuangyin, what is the matter? Shao Qing: deviation of the need to do four-wheel alignment check, the angle of the caped wheel camber and the toe of these two data. Because the value of four-wheel positioning if it is not correct, there will be deviation from time to time left and right case. Free clearance of about 5 mm may be the width of the ball after the wheel tie bar, causing the free gap is too large, or rack-type steering gear with a slight wear and tear, there will be free Kuang.
