C: INSPECTION
Check all disassembled parts for wear, damage or other problems. Repair or replace the defective parts as
necessary.
CAUTION:
Although the surface layer materials of rubber hoses have excellent weathering resistance, heat re-
sistance 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. Wipe off hoses immediately if any of these come into contact with the hoses.
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 accord-
ingly, it is necessary to perform careful inspection frequently when the vehicle is used in hot weather
areas, cold weather areas and 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 hos-
es, the oil pump, the fluid, etc. due to over heat.

1. NOISE & VIBRATION
CAUTION:
Do not keep the relief valve operated over five seconds at any time or inner parts of the oil pump may
be damaged due to rapid increase of fluid temperature.
NOTE:
•A screeching noise may be heard immediately after the engine start in extremely cold conditions. In this
case, if the noise goes off during warm-up there is no abnormal function in the system. This is due to the fluid
characteristics in extremely cold condition.
•The oil pump normally makes a small whining noise due to its mechanism. Even if a noise is 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 driving.
•When turning the steering wheel with the brake applied when the vehicle is parked, a screeching noise
may be generated by the brake disc and pads. This is not a fault in the steering system.
•There may be a small vibration around the steering devices when turning the steering wheel at standstill,
even though the component parts are operating properly.
Hydraulic systems are likely to generate this kind of vibration as well as working noise and fluid noise be-
cause of combined conditions, i.e., road surface and tire surface, engine speed and turning speed of steering
wheel, fluid temperature and braking condition.
These conditions do not indicate a problem in the system.
Confirm vibration for an AT model, by applying the parking brake on a concrete surface, shifting into the “D”
range, and turning the steering wheel repeatedly from slow to rapid, step by step.
Tr o u b l e P o s s i b l e c a u s e C o r r e c t i v e a c t i o n
Hiss noise (continuous)
While engine is running.
Relief valve emits operating sound when steering wheel is
completely turned in either direction. (Do not keep this
condition over five seconds.)
Normal
Relief valve emits operating sound when steering wheel is
not turned. This means that the relief valve is defective. Replace the oil pump.

While engine is running.
Interference with adjacent parts
Check the clearance.

2. MEASUREMENT OF STEERING EFFORT
Step Check Yes No
1CHECK STEERING EFFORT.
1) Stop the vehicle on paved road.
2) Start the engine.
3) Run the engine at idle.
4) Install a spring scale on the steering wheel.
5) Pull the spring scale at a right angle to the
steering wheel, and measure both right and left
steering wheel efforts.
NOTE:When turning the steering more quickly than
necessary from a direction to the other direction
at an engine speed over 2,000 rpm, steering ef-
fort may be heavy. This is caused by flow char-
acteristic of the fluid in the oil pump and is not a
defect.
Is the steering effort less than
29.4 N (3.0 kgf, 6.6 lb)?
Go to step 2.Adjust the back-
lash.
2CHECK STEERING EFFORT.
1) Stop the engine.
2) Pull the spring scale at a right angle to the
steering wheel, and measure both right and left
steering wheel efforts.
Is the steering effort less than
294.2 N (30 kgf, 66.2 lb)?
Go to step 3.Perform the
adjustment.
3CHECK STEERING WHEEL EFFORT.
1) Remove the universal joint.
2) Measure the steering wheel effort.
Is steering effort less than 2.26
N (0.23 kgf, 0.51 lb)?
Go to step 4.Check, adjust and
replace if neces-
sary.
4CHECK STEERING WHEEL EFFORT.
Measure the steering wheel effort.
Is the difference of steering
effort between right and left
less than 20%?
Go to step 5.Check, adjust and
replace if neces-
sary.
5CHECK UNIVERSAL JOINT.
Measure the swing torque of the joint (yoke of
steering column side). INSPECTION, Universal Joint.>
Is the swing torque of the uni-
versal joint less than 7.3 N
(0.74 kgf, 1.64 lb)?
Go to step 6.Replace with a
new part.
6CHECK UNIVERSAL JOINT.
Measure the swing torque of the joint (yoke of
gearbox side). Universal Joint.>
Is the swing torque of the uni-
versal joint less than 3.8 N
(0.39 kgf, 0.86 lb)?
Go to step 7.Replace with a
new part.
7CHECK FRONT WHEEL.

Does the front wheels have
unsteady revolution or rattling,
or does the brake drag?
Inspect, readjust
and replace if nec-
essary.
Go to step 8.
8CHECK TIE–ROD ENDS.
Remove the tie–rod ends.
If the tie-rod ends of suspen-
sion have unsteady revolution
or rattling?
Inspect and
replace if neces-
sary.
Go to step 9.
9BALL JOINT CHECK.
Remove the ball joint.
If the ball joints of suspension
have unsteady revolution or
rattling?
Inspect and
replace if neces-
sary.
Go to step 10.

Measure the rotating of gearbox.
GEARBOX, INSPECTION, Steering Gear-
box.>
Is the rotating resistance of
steering gearbox less than
10.5 N (1.1 kgf, 2.4 lb)? Is the
difference between right and
left sides less than 20%?

lash, and if ineffec-
tive, replace the
faulty par ts.
11 CHECK GEARBOX.

steering gearbox less than 400
N (41 kgf, 90 lb)? Is the differ-
ence between the right and left
sliding resistance less than
20%?
Steering effort is
normal.
Readjust the back-
