Causes of steering vibration.

(useful articles)

Vibration steering occurs for many reasons. There are a variety of symptoms, which can determine the causes of vibration of the steering wheel. The steering wheel may vibrate on a certain speed, and continuously. Steering vibration can occur during acceleration, driving and braking of the car, as well as when the engine is just idling.

Vibration steering at speeds often arises from the unbalanced rotating masses. There may be various reasons for this phenomenon, which can also at the same time complement each other. Vibration can occur due to wheel drive mud clogging. Some models are designed wheels so that dirt can accumulate in certain places, and zasyhaya create unbalanced mass. The first thing to do when a steering vibration is to wash all the wheels and make sure there is no dirt on them.

Vibration steering may occur if poorly balanced wheel. This problem can be solved only by the tire changer service. If after visiting the tire shop appeared steering vibration when accelerating and driving, we can confidently say that the reason for this is a bad wheel balancing.

Beating steering may occur due to improper geometry of the wheel rim or the tire. Such repairs may cause the wrong bus or drive, or a strong blow from which, for example, there are "bumps" on the rubber. Wheel with such defects can balance the ideal, but the runout will still be present, creating the dynamic loads on the suspension and steering vibration.

Also cause steering vibration can serve as incorrect installation of the wheels, or if the disk geometry does not match the hub. A common mistake is considered to be improper tightening wheel bolts or nuts with a conical base. Nuts and bolts should be tightened conical base, alternating with the opposite, and only if the wheel is suspended.

Vibration steering when braking may also occur because of the unbalanced mass of the wheel. But the main cause of the vibration of the steering wheel when braking a car is a strong uneven wear of the brake pads or discs. To eliminate this problem is to replace the brake discs and pads with new ones. A cheaper way to fix this problem can be groove brake discs, if it allows them to design and size.

The cause steering vibration during acceleration, driving and braking can be deformation of the wheel hub bearing or other elements of the suspension of the car. To diagnose this problem is measuring runout installed on the vehicle when it rotates in limbo. The deformation of the wheel hubs is often the result of a collision at high speed on a speed bump or a big hole.

Vibration idling vehicles can occur for many reasons. The most common problem is the failure of the engine mounts and the gearbox. To eliminate this problem is to replace the support that out of order. The vibrations on the steering wheel may occur when an unstable operation of the engine at idle. In this case, check the spark.

Vibration can occur on the steering wheel due to an imbalance or the fan unit. If the radiator clogged air conditioner, the air conditioner's fan will continue to run at maximum speed, which can also cause steering vibration.

Whatever the reason, the vibration of the steering wheel are not normal, but there is a kind of "critical signal" the driver of a car breakdown. When the vibration on the steering wheel should immediately identify and eliminate the cause.
