For drivers, control of a car is the main control of the steering wheel. The steering wheel can not only control the direction of the vehicle, but also can be used to identify the failure of the vehicle,so the first step is to understand your safe driving wheel.

Traffic of shaking. The vehicle speed to more than speed, chassis periodic noise, cab and doorshaking, the steering wheel vibration, until numb hands, this is because the direction of the drivedevice of dynamic balance is destroyed, the transmission shaft and the spline shaft and the spline sleeve caused by excessive wear.

When the steering too heavy. The steering wheel feels very laborious, it is likely to be turned to the lubrication of bearings, ball head rod, longitudinal steering tie rod adjustment is too tight orlack of, or before the car frame, or bending deformation or tire pressure caused by the lack ofcommon, as the front tyre.

Difficult control of the steering wheel. When driving a vehicle automatic direction deviation, togrip the steering wheel to adjust. This is caused by the tire pressure, bearing clearance,wheelbase and other issues.

Directions hair waves. Is often the front wheel shimmy in driving by, and when the vehicle istraveling at a high speed, the problem may appear as a front wheel assembly, a shaft assemblydynamic balance is destroyed, the transmission shaft assembly parts loosening, damper failure,mechanical wear loose steering system, front wheel alignment problems caused by improper.
