21.Steering System (Power
Steering)
A: INSPECTION
1. STEERING WHEEL
1) Set the steering wheel in a straight-ahead posi-
tion, and check the wheel spokes to make sure
they are correctly set in their specified positions.
2) Lightly turn the steering wheel to the left and
right to determine the point where front wheels start
to move.
Measure the distance of the movement of steering
wheel at the outer periphery of wheel.
Steering wheel free play:
0 — 17 mm (0 — 0.67 in)
Move the steering wheel vertically toward the shaft
to ascertain if there is play in the direction.
Maximum permissible play:
0.5 mm (0.020 in)
3) Drive the vehicle and check the following items
during operation.
(1) Steering force:
The effort required for steering should be
smooth and even at all points, and should not
vary.
(2) Pulled to one side:
Steering wheel should not be pulled to either
side while driving on a level surface.
(3) Wheel runout:
Steering wheel should not show any sign of
runout.
(4) Return factor:
Steering wheel should return to its original posi-
tion after it has been turned and then released.
2. STEERING SHAFT JOINT
When the steering wheel free play is excessive,
disconnect the universal joint of steering shaft and
check it for any play and yawing torque (at the point
of the crossing direction). Also inspect for any dam-
age to sealing or worn serrations. If the joint is
loose, retighten the mounting bolts to the specified
torque.
Tightening torque:
24 N·m (2.4 kgf-m, 17.4 ft-lb)
3. GEARBOX
1) With the vehicle placed on a level surface, turn
the steering wheel 90° in both the left and right di-
rections.
While the wheel is being rotated, reach under the
vehicle and check for looseness in gearbox.
Tightening torque:
60 N·m (6.1 kgf-m, 44.1 ft-lb)
2) Check the boot for damage, cracks or deteriora-
tion.
3) With the vehicle placed on a level surface, quick-
ly turn the steering wheel to the left and right.
While steering wheel is being rotated, check the
gear backlash. If any noise is noticed, adjust the
gear backlash.
4) Apply liquid gasket to at least 1/3 of entire perim-
eter of adjusting screw thread.
5) Tighten the adjusting screw to 25 N·m (2.5 kgf-
m, 18.1 ft-lb) and then loosen.

6) Tighten the adjusting screw to 3.9 N·m (0.40 kgf-
m, 2.9 ft-lb) and then loosen 20°.
7) Install the lock nut. While holding the adjusting
screw with wrench, tighten the lock nut using ST.
ST 926230000 SPANNER
Tightening torque (lock nut):
25 N·m (2.5 kgf-m, 18.1 ft-lb)
Hold the adjusting screw with wrench to prevent it
from turning while tightening the lock nut.
4. TIE-ROD
1) Check the tie-rod and tie-rod ends for bends,
scratches or other damage.
2) Check the connections of knuckle ball joints for
play, inspect for damage on dust seals, and check
free play of ball studs. If the castle nut is loose, re-
tighten it to the specified torque, then tighten it fur-
ther up to 60°until the cotter pin hole is aligned.
Tightening torque:
27 N·m (2.75 kgf-m, 19.9 ft-lb)
3) Check the lock nut on the tie-rod for tightness. If
it is loose, retighten it to the specified torque.
Tightening torque:
85 N·m (8.7 kgf-m, 63 ft-lb)
5. POWER STEERING FLUID LEVEL
NOTE:
•At power steering fluid temperature 20°C (68°F);
read the fluid level on the “COLD” side.
•At power steering fluid temperature 80°C
(176°F); read the fluid level on the “HOT” side.
1) Place the vehicle with engine “OFF” on a level
surface.
2) Check the fluid level using the scale on the out-
side of the reservoir tank. If the level is below MIN,
add fluid to bring it up to MAX.
NOTE:
If fluid level is at MAX level or above, drain fluid to
keep the level in the specified range of indicator by
using a syringe or the like.
Recommended fluid:
Refer to “RM” section. RECOMMENDED MATERIALS, Recommend-
ed Materials.>
Fluid capacity:
0.9 2 (1.0 US qt, 0.8 Imp qt)
6. POWER STEERING FLUID FOR LEAKS
Inspect the underside of oil pump and gearbox of
power steering system, hoses, pipes and their cou-
plings for fluid leaks.
If the fluid leaks are found, retighten their fitting
bolts (or nuts) and/or replace their parts.
NOTE:
•Wipe the leaked fluid off after correcting fluid
leaks.
•Also pay attention to clearances between hoses
(or pipes) and other parts when inspecting fluid
leaks.
(A) Apply liquid gasket to at least 1/3 of entire
perimeter

7. HOSES OF OIL PUMP FOR DAMAGES
Check the pressure hose and return hose of oil
pump for crack, swell or damage. Replace the hose
with a new one if necessary.
NOTE:
Prevent hoses from turning and/or bending when
installing hoses.
8. POWER STEERING PIPES FOR DAMAG-
ES
Check the power steering pipes for corrosion and
damage.
Replace the pipes with new ones if necessary.
9. GEARBOX BOOTS
Inspect both sides of the gearbox boot as follows,
and correct the defects if necessary.
1) Positions (A) and (B) of the gearbox boot are fit-
ted correspondingly in grooves (A) and (B) of the
gearbox and rod (C).
2) Clips are fitted outside of positions (A) and (B) of
boot.
3) Boot does not have crack or hole.
NOTE:
Rotate (B) position of gearbox boot against the tor-
sion produced by the adjustment of toe-in etc. Ap-
ply grease to the groove (C).
10.FITTING BOLTS AND NUTS
Inspect the fitting bolts and nuts of oil pump and
bracket for looseness, and retighten them if neces-
sary.
Inspect and/or retighten them when engine is cold.
