The steering wheel is an automobile-mounted steering device that transmits the steering force of the driver to the steering gear after the steering force of the driver is applied. It plays an important role in driving. The steering instability of the steering wheel will cause the driver to feel dizzy when cornering, and even cause an accident. So how do you troubleshoot an unstable steering wheel?
First of all, you need to check the steering linkage mechanism of the car, such as the steering gear connection rod and ball head. If the connection is not tightened or the ball head is worn, it will cause the steering instability. The solution is to inspect the relevant components and replace them in the event of wear and tear.
Second, it is necessary to check the cars tire pressure. The tire pressure of over-inflated tires is too high and the center of gravity of the tire is lowered. Poor cornering performance is also easy to occur. The solution is to adjust the tire pressure to the manufacturers required pressure.
Third, check the car alignment situation. If the cars up and down, left and right, slit are unbalanced and changed, it is easy to cause steering instability. Solution: take the car to a professional four-wheel positioning station for detection and repair.
Fourth, it may be that the car steering is too light due to the failure of the power steering system itself. The solution is to check the power steering system and identify faults.
Fifth, it is possible that the steering ability of the car is influenced by the addition of accessories, such as roof rack, roof box, etc., which increases the load of the car. Solution: clean the accessories installed on the car.
In addition, the instability of the steering wheel may also be caused by other factors, such as uneven road, poor quality power steering fluid, dirt on the surface of the tire, cupping of the tire, leaking of the power steering system, etc.
To sum up, there are many reasons for the unsteadiness of the steering wheel, so it is necessary to check the parts of the car in detail if you ever encounter an unsteady steering wheel. If you are not sure, it is recommended that you take the car to a professional 4S shop for maintenance.
