•ADJUSTMENT
When adjusting, adjust it to the following value.
Toe-in:
2±1.5 mm (0.08±0.06 in)
1) Loosen the self-locking nut on the inner side of the front lateral link.
NOTE:
When loosening or tightening the adjusting bolt, hold the bolt head and turn the self–locking nut.
2) Turn the adjusting bolt until toe–in is within the specification.
NOTE:
When the left and right wheels are adjusted for toe–in at the same time, moving one mark on the scale chang-
es toe–in by approx. 3 mm (0.12 in).
3) Attach and tighten a new self–locking nut.
Tightening torque:

7. THRUST ANGLE
•INSPECTION
1) Park the vehicle on a level surface.
2) Move the vehicle 3 to 4 meters (10 to 13 feet)
straight forward.
3) Draw the center of loci for both the front and rear
axles.
4) Measure distance “L” between the center lines of
the axle loci.
Thrust angle:
0°±30′
Less than 30′ when “L” is 24 mm (0.9 in) or
less.
•ADJUSTMENT
When adjusting, adjust it to the following value.
Thrust angle:
0°±20′
Less than 20′ when “L” is 16 mm (0.6 in) or
less.
1) Make thrust angle adjustments by turning the
toe–in adjusting bolts of the rear suspension equal-
ly in the same direction.
2) When one rear wheel is adjusted in a toe-in di-
rection, adjust the other rear wheel equally in toe-
out direction, in order to make the thrust angle ad-
justment.
3) When the left and right adjusting bolts are turned
by one graduation, the thrust angle will change ap-
prox. 19′ (“L” is approx. 16 mm (0.63 in)).
NOTE:
Thrust angle is a mean value of left and right wheel
toe angles in relation to the vehicle body center
line. Vehicle is driven straight in the thrust angle di-
rection while slanting in the oblique direction de-
pending on the degree of the mean thrust angle.
Thrust angle: r = (α – β)/2
α: Rear RH wheel toe–in angle
β: Rear LH wheel toe–in angle
Substitute only the positive toe–in values from each
wheel into α and β in the equation.

Steering Gearbox
POWER ASSISTED SYSTEM (POWER STEERING)
1) Lift-up the vehicle.
2) If a fluid leak is found, clean the fluid completely
from the suspect area, and turn the steering wheel
approx. 30 to 40 times to the left and right from lock
to lock, with the engine running, and check again
for leaks immediately, and also after a few hours
have passed.
3) Cause and solution for oil leakage from “a”
The oil seal is damaged. Replace the valve assem-
bly with a new one.
4) Cause and solution for oil leakage from “b”.
The torsion bar O–ring is damaged. Replace the
valve assembly with a new one.
5) Cause and solution for oil leakage from “c”.
The oil seal is damaged. Replace the valve assem-
bly or oil seal with a new one.
6) Cause and solution for oil leakage from “d”.
The pipe is damaged. Replace the faulty pipe or O-
ring.
7) Cause and solution for oil leakage from “g”.
The hose is damaged. Replace the hose with a
new one.
8) If leak is other than a, b, c, d or g, or if oil is leak-
ing from gearbox, move the right and left boots to-
ward tie-rod end side, respectively, with the
gearbox mounted to the vehicle, and remove fluid
from surrounding portions. Then, turn the steering
wheel from lock to lock about thirty to forty times
with the engine running, and make comparison of
the leaked portion immediately after and several
hours after this operation.
(1) Leakage from “e”
The cylinder seal is damaged. Replace the rack
bushing with a new one.
(2) Leakage from “f”
There are two possible causes. Perform the fol-
lowing step first. Remove the pipe assembly B
from the valve housing, and close the circuit us-
ing ST.
ST 926420000 PLUG
Turn the steering wheel from lock to lock ap-
prox. 30 to 40 times with the engine running,
then inspect the leaked portion immediately af-
ter and several hours after this operation.
•If leakage from “f” is noted again:
The oil seal of pinion & valve assembly is dam-
aged. Replace the pinion & valve assembly with a
new one. Or replace the oil seal and the parts that
are damaged during disassembly with new ones.
•If oil stops leaking from “f”:
The oil seal of rack housing is damaged. Replace
the oil seal and parts that are damaged during dis-
assembly with new ones.
F: ADJUSTMENT
1) Adjust the front toe.
Standard of front toe:
IN 3 — OUT 3 mm (IN 0.12 — OUT 0.12 in)
2) Adjust the steering angle of the wheels.
Specification of steering angle:
3) If the steering wheel spokes are not horizontal
when wheels are set in the straight ahead position,
or error is more than 5° on the periphery of the
steering wheel, correctly re-install the steering
wheel.
4) If the steering wheel spokes are not horizontal
with vehicle set in the straight ahead position after
this adjustment, correct it by turning the right and
left tie–rods in the opposite direction from each oth-
er by the same angle.

General Diagnostic Table
POWER ASSISTED SYSTEM (POWER STEERING)
10.General Diagnostic Table
A: INSPECTION
*1 If the tires or wheels are wider than standard, the load to the power steering system is increased. Accordingly, in a condition,
for example before fluid warms-up, relief valve may work before reaching maximum turning angle. In this case, steering effort
may be heavy. When the measured hydraulic pressure is normal, there is no abnormal thing. *2 In cold weather, flow resistance will increase due to the cold hydraulic fluid, and steering effort will be heavier. After warming-up en-
gine, turn the steering wheel from stop to stop several times to warm-up fluid. If steering effort reduces normally, function is normal. *3 I n c o l d w e a t h e r o r w i t h i n s u f f i c i e n t w a r m – u p o f t h e e n g i n e , s t e e r i n g e f f o r t m a y b e h e a v y d u e t o e x c e s s i v e d r o p o f i d l e r p m w h en
turning the steering wheel. In this case, start the vehicle with increasing engine speed than usual. If steering effort reduces nor-
mally, function is normal.
