3) How to install the joint.
(1) Push the long yoke of the joint, all the way into the
serrated portion of the steering shaft, setting the bolt
hole in the cutout.
(2) Then pull the short yoke all way out of the serrated
portion of the gearbox, setting the bolt hole in the cut-
out.
(3) Insert the bolt through the short yoke, pull the joint
and confirm that the bolt is on cutout of the gearbox.

1) Feed the specified fluid with its level being about 5 cm
(2.0 in) lower than the mouth of tank.
2) Continue to turn steering wheel slowly from lock to lock
until bubbles stop appearing in the tank while keeping the
fluid at that level.
3) In case air is absorbed to deliver bubbles into piping
because the fluid level is lower, leave it about half an hour
and then do the step 2) all over again.
4) Start, and idle the engine.
5) Continue to turn steering wheel slowly from lock to lock
again until bubbles stop appearing in the tank while keep-
ing the fluid at that level.
It is normal that bubbles stop appearing after three times
turning of steering wheel.
6) In case bubbles do not stop appearing in the tank, leave
it about half an hour and then do the step 5) all over again.
7) Stop the engine, and take out safety stands after jack-
ing up vehicle again.
Then lower the vehicle, and idle the engine.
8) Continue to turn steering wheel from lock to lock until
bubbles stop appearing and change of the fluid level is
within 3 mm (0.12 in).
9) In case the following happens, leave it about half an
hour and then do step 8) again.
(1) The fluid level changes over 3 mm (0.12 in).
(2) Bubbles remain on the upper surface of the fluid.
(3) Grinding noise is generated from oil pump.

10) Check the fluid leakage at flare nuts after turning
steering wheel from lock to lock with engine running.
CAUTION:

Before checking, wipe off any fluid on flare nuts and
piping.

In case the fluid leaks from flare nut, it is caused by
dust (or the like) and/or damage between flare and
tapered seat in piping.

So remove the flare nut, tighten again it to the speci-
fied torque after cleaning flare and tapered seat. If flare
or tapered seat is damaged, replace it with a new one.
11) Inspect fluid level on flat and level surface with engine
“OFF”by indicator of filler cap.
If the level is at lower point or below, add fluid to keep the
level in the specified range of the indicator. If at upper point
or above, drain fluid by using a syringe or the like.

*1 If tires and/or rims are wider, the load to power steering system is the more. Accordingly, in a
condition, for example before fluid warms-up, relief valve may work before maximum turning angle.
In this case, steering effort may be heavy. When measured hydraulic pressure is normal, there is
no abnormal thing.
*2 In cold weather, steering effort may be heavy due to increased flow resistance of cold fluid. After
warming up engine, turn steering wheel from stop to stop several times to warm up fluid. Then if
steering effort reduces normally, there is no abnormal thing.
*3 In cold weather or with insufficient warm-up of engine, steering effort may be heavy due to exces-
sive drop of idling when turning steering wheel. In this case, it is recommended to start the vehicle
with increasing engine speed than usual. Then if steering effort reduces normally, there is no
abnormal thing. Measure hydraulic pressure.

CAUTION:
It is likely that although one judges fluid leakage, there
is actually no leakage. This is because the fluid spilt
during the last maintenance was not completely wiped
off. Be sure to wipe off spilt fluid thoroughly after
maintenance.

fluid will not bleed out under the conditions described, and have the customer check the fluid level and its quality more fre-
quency than usual.

3. REFRIGERANT
Do not put CFC-12 refrigerant into a HFC-134a air condi-
tioning system. Also, do not put HFC-134a refrigerant into
a CFC-12 air conditioning system. If the wrong refrigerant
is used, poor lubrication will result and the compressor
itself may be destroyed.
G4M0979
4. HANDLING OF REFRIGERANT
Because refrigerant boils at approx. 30°C (22°F) at sea
level, it is cold enough to give you severe frostbite. Always
wear goggles to protect your eyes and gloves to protect
your hands. Also, even under the pressures normally found
in CFC-12 containers, refrigerant will boil with the addition
of heat. This could raise the pressure inside the container
to a dangerous level.
Never expose a can of HFC-134a to direct sunlight, or to
temperatures over 40°C (104°F). One more thing to
remember about HFC-134a is that when it is exposed to an
open flame or to hot metal, it forms phosgene, a deadly
gas. Do not discharge HFC-134a into the atmosphere on
purpose. Always read and follow the precautions on the
HFC-134a bottle.

1. Safety Precautions

2. Basic Information
1) The combination of moisture and refrigerant forms acid,
therefore, moisture should not be allowed to enter the
refrigerant.
2) Refrigerant oil readily absorbs moisture, therefore, keep
refrigerant oil containers tightly capped.
3) The process of evacuating the system is performed to
remove small amounts of moisture. This is accomplished
by lowering the pressure inside the system, which allows
the moisture to boil off, in much the same way that a pot
of water will boil away to nothing given enough time. The
evacuation process does not suck the moisture out of the
system.
4) A minimum level of vacuum must be reached to satis-
factorily evacuate the system. This minimum level of
vacuum depends on the temperature inside the system.
The chart below shows the level of vacuum required to boil
water at various temperatures.
Additionally, the vacuum level shown on a gauge will read
approx. 4 kPa (25 mmHg, 1 inHg) less for each 304.8 m
(1,000 ft) above sea level, due to the decrease in atmo-
spheric pressure at altitude.
