I believe that many friends have encountered the regular abnormal noise of the low-speed front wheels on flat roads, so what causes the abnormal noise?
Law of knocking of low-speed front wheel on flat road surface The abnormal sound of low-speed front wheel on flat road surface may be caused by the following problems.
1. The steering ball joint is loose. Excessive wear of the ball head will loosen, and the vehicle will make a knocking sound when driving on uneven roads. This problem can only be solved by replacing the lower arm ball head.
2. Oil leakage or deformation of shock absorber. When the shock absorber is hit or aged, the shock absorption effect will be greatly reduced. At this time, there is no abnormal sound inside the shock absorber because there is no lubrication. If the shock absorber is too aging, then we can only solve it by replacing it.
3. The wheel hub is not round. If the hub is impacted too much, it will cause the hub to be out of round. When the hub is not round, there will be a regular knocking sound, accompanied by a regular knocking sound. We can solve this problem by repairing or replacing the wheel hub.
Knock, knock, knock. Is the shock absorption too hard? It's possible. If the shock absorber of your car becomes hard due to aging, it needs to be replaced in time. Generally speaking, abnormal chassis noise is not normal, so it is best to go to the 4S shop for a comprehensive inspection.
Does the steering gear sound abnormal and need to be replaced? It depends. If the abnormal sound of the steering gear only occurs when your vehicle hits the full direction, then there is no need to replace it, because this situation is normal and is not caused by the steering gear problem. If there is abnormal sound when the steering gear rotates during normal driving, it needs to be replaced, which is probably caused by excessive wear of the steering gear M.
