Oil pump makes whine or growl noise slightly due to its mechanism . Even if the noise can be heard when
steering wheel is turned at standstill there is no abnormal function in the system provided that the noise
eliminates when the car is running.
When stopping with service brake and/or parking brake applied, power steering can be operated easily due
to its light steering effort . If doing so, the disk rotates slightly and makes creaking noise . The noise is
generated by creaking between the disk and pads . If the noise goes off when the brake is released, there is
no abnormal function in the system .
There may be a little vibration around the steering devices when turning steering wheel at standstill, even
though the component parts are properly adjusted and have no defects .
Hydraulic systems are likely to generate this kind of vibration as well as working noise and fluid noise
because of combined conditions, i .e.,
Road surface and tire surface, Engine speed and turning speed of steering wheel, Fluid temperature and
braking condition.
This phenomena does not indicate there is some abnormal function in the system.
The vibration can be known when steering wheel is turned repeatedly at various speeds from slow to rapid
step by step with parking brake applied on concrete road in "D" range.
