Extraneous noise during the steering work The hissing sound in steering transfer

All amplifiers of steering publish additional noise. One of the most widespread is a hissing sound when the steering wheel is turned on the motionless car. This sound will be most obvious at turn of a steering wheel at the pressed brake pedal. There are no relations between this noise and work of steering. Do not replace the valve if the "hissing" noise does not become extraordinary. The new valve will also publish small noise.
The roaring sound in steering transfer Side play between hoses and a body of the car Lay properly and fix hoses
Steering transfer is not fixed Fix steering transfer Fix steering transfer
The tip of steering draft and / or the spherical hinge is not fixed Delay connections
The tip of steering draft and / or the spherical hinge is worn-out Replace
Noise in the pump of the amplifier of steering Low level of liquid Add liquid
Air in liquid Remove air
Bolts of fastening of the pump are not tightened Tighten bolts

Prevention

Quiet noise has to be heard right after launch of the engine at the air temperature of -20 °C. It is connected with properties of the liquid applied in the amplifier of steering and is not a malfunction sign.
