Q: Steering wheel knocking sound when stationery

你好呀。If the wheel is rotating when the steering is turned and you hear a knocking sound, then this is the sound of a constant velocity (CV) shaft bearing failing. Remove the front wheels and check around the CV shaft and see if the boot has a rip or it is missing a clamp. If you are having to更换简历轴，我建议更换两个驱动CV轴，以防止轴的任何破裂。如果您需要在车辆方面进一步帮助，请寻找一名专业人士，例如来自Mechanic的专业人员，万博体育入口diagnose the knocking noise。之后，他们可以通过正确的维修进行跟进。
