Damaged valve in oil pump, gear-
boxReplace oil pump, bad parts of
gearbox.
Looseness of play of steering,
suspension partsRetighten.
*8 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 stand still there is no abnormal function in the system provided that the noise eliminates when the vehicle is
running.
*9 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.
*10 There may be a little vibration around the steering devices when turning steering wheel at standstill, even though the com-
ponent 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 com-
bined 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 and in“D”range for automatic transmission vehicle.

Too many times use in extremely
cold weatherReplace.
Instruct customers.
*11 Although surface layer materials of rubber hoses have excellent weathering resistance, heat resistance and resistance for
low temperature brittleness, they are likely to be damaged chemically by brake fluid, battery electrolyte, engine oil and
automatic transmission fluid and their service lives are to be very shortened. It is very important to keep the hoses free
from before mentioned fluids and to wipe out immediately when the hoses are adhered with the fluids.
Since resistances for heat or low temperature brittleness are gradually declining according to time accumulation of hot or
cold conditions for the hoses and their service lives are shortening accordingly, it is necessary to perform careful inspec-
tion frequently when the vehicle is used in hot weather areas, cold weather area and/or a driving condition in which many
steering operations are required in short time. Particularly continuous work of relief valve over 5 seconds causes to reduce
service lives of the hoses, the oil pump, the fluid, etc. due to over heat.
So, avoid to keep this kind of condition when servicing as well as driving.
