As violations in steering affect several systems, it is necessary to take all these systems into account when diagnosing malfunctions. Not to be misled by false symptoms, it is necessary to carry out road tests of the car always at first.

Check the amplifier of steering for existence of leaks. Also check the level of working liquid of the amplifier of steering and a tension of a driving belt of the pump.

During the operation of the amplifier of steering there is always an insignificant noise. The hissing sound which is not irritating the driver which is heard when the steering wheel is turned on the standing car is most widespread. Also this noise is most susceptible at turn of a steering wheel when braking. This sound proceeds from hydraulic liquid under pressure. Between this noise and operation of the steering mechanism there is no communication.

       PREVENTION

Do not replace the valve if the "hissing" noise not too strong. The new valve also publishes insignificant noise and is not always the solution of this problem.

Formation of foam, increase in viscosity of liquid of the amplifier of steering, low level of liquid and possible low pressure

It can be caused by availability of air in liquid and loss of liquid in connection with the internal leak in the pump causing a liquid overflowing. Check for existence of leaks and eliminate them. Remove air from the hydraulic drive of the amplifier of steering.

       PREVENTION
