STEERING ANGLE
When tie rod end was replaced, check toe and then also steering
angle with turning radius gauges.
If steering angle is not correct, check if right and left tie-rods are
equal in length (ªAº in left figure).
Steering angle
inside: 35 3
outside: 33 3
NOTE:
If tie rod lengths were changed to adjust steering angle, rein-
spect toe-in.
Reference Information:
Side slip:
For inspecting front wheel side slip with side slip tester:
Side slip limit: Less than 3 mm / m
(Less than 0.118 in. / 3 ft)
If side slip exceeds above limit, toe-in or front wheel alignment may
out not be correct.

HYDRAULIC PRESSURE IN P / S CIRCUIT
HYDRAULIC PRESSURE CHECK
1) After cleaning joint of high pressure hose and P / S pump thor-
oughly, disconnect hose from pump and install special tool (oil
pressure gauge, attachment and hose).
Tighten each flare nut to specified torque.
CAUTION:
Take care not to cause damage to A / C condenser during
service operation, if equipped.
Special Tool
(A): 09915-77410 (Oil pressure gauge)
(B): 09915-77420
2) Check each connection for fluid leakage and bleed air.
Refer to ªAIR BLEEDING PROCEDUREº in this section.
3) With engine idling, turn steering wheel and warm up engine till
temperature of fluid in P/S fluid reservoir rises to 50 ± 60C (122
± 140F).
4) Check back pressure by measuring hydraulic pressure with en-
gine idling and hands off steering wheel.
Back pressure: Lower than 1000 kPa (10 kg / cm
2, 142 psi)
When back pressure is higher than specified values, check con-
trol valve and piping for clogging.

5) Check relief pressure
Increase engine speed to about 1,500 r / min (rpm). Close
gauge valve gradually while watching pressure increase indi-
cated by gauge and take reading of relief pressure (maximum
hydraulic pressure).
Relief pressure:

(62 ± 70 kg / cm
2, 882 ± 995 psi) G16 Type engine. . . . . . .

7050 ± 7850 kPa
(70.5 ± 78.5 kg / cm
2, 1003 ± 1116 psi) H25 Type engine. .
When it is higher than specified values, possible cause is mal-
function of relief valve.
When it is lower than specified values, possible cause is either
failure of P / S pump or settling of relief valve spring.
CAUTION:
Be sure not to close gauge valve for longer than 10 se-
conds.
Next, open gauge valve fully and increase engine speed to
about 1,500 r / min (rpm). Then turn steering wheel to the left
or right fully and take reading of relief pressure.
Relief pressure:
6200 ± 7000 kPa
(62 ± 70 kg / cm
2, 882 ± 995 psi) G16 Type engine. . . . . . .
6700 ± 7500 kPa

7050 ± 7850 kPa
(70.5 ± 78.5 kg / cm
2, 1003 ± 1116 psi) H25 Type engine. .
When it is higher than specified values, possible cause is mal-
function of relief valve.
When it is lower than specified values, possible cause is failure
in steering gear box. Replace gear box.
CAUTION:
Be sure not to hold steering wheel at fully turned posi-
tion for longer than 10 seconds.
BOOT
STEERING RACK BOOT CHECK
Check boot for crack and damage which, if any, means possibility
of rusty gear, entry of dust or lack of grease. Also, check if any of
such faulty conditions exists.
Check steering rack boot for dent or breakage.
If there is a dent, keep boot in most compressed state for some se-
conds to correct dent.

The metric term for tire inflation pressure is the kilopascal (kPa).
Tire pressures will usually be printed in both kPa and psi on the Tire

WHEELS REPLACEMENT
Wheels must be replaced if they are bent, dented, have excessive
lateral or radial runout, leak air through welds, have elongated bolt
holes, if lug nuts won't stay tight, or if they are heavily rusted.
Wheels with greater runout than shown in left figure may cause ob-
jectional vibrations.
Wheels for replacement must be equivalent to the originally
equipped wheels in load capacity, diameter, rim width, off-set and
mounting configuration. A wheel of improper size or type may affect
wheel and bearing life, brake cooling, speedometer / odometer cal-
ibration, ground clearance to the body and chassis.
To measure the wheel runout, it is necessary to use accurate dial
indicator. The tire may be on or off the wheel. The wheel should be
installed to the wheel balancer of the like for proper measurement.
Take measurements of both lateral runout and radial runout at both
inside and outside of the rim flange. With dial indicator set in place
securely, turn the wheel one full revolution slowly and record every
reading of the indicator.
When the measured runout exceeds the specification and correc-
tion by the balancer adjustment is impossible, replace the wheel.
If the reading is affected by welding, paint or scratch, it should be
ignored.
Lateral runout limit ªaº: 1.20 mm (0.047 in.)
Radial runout limit ªbº: 1.20 mm (0.047 in.)
METRIC LUG NUTS AND WHEEL STUDS
All models use metric lug nuts and wheel studs (size M12 x 1.25).
