SERVICE ADJUSTMENT PROCEDURES
HUB END PLAY INSPECTIONNO2FAAB --- ’
1. Jack up the vehicle and remove the front wheels.
2.Remove the disc brake caliper and suspend it with a wire.
(Refer to GROUP
5-Service Adjustment Procedures.)
3.Attach a dial indicator as shown in the illustration, and thenmeasure the axial play while moving the hub back and
forth.Limit
: 0.2 mm (.008 in.) or less
NOTE
Secure the brake disc and hub by the wheel nut so that thebrake disc won’t come off the hub.
4.If axial play exceeds the limit, disassemble and check parts.
FRONT WHEEL ALIGNMENTNOZFBAQ
NOTEThe front suspension assembly must be free of worn, loose or
damaged parts prior to measurement of front wheel align-

NOTEBe cautious to ensure that the differential carrier oil seal is
not damaged by the drive shaft spline.
3. DISCONNECTION OF PROPELLER SHAFT
(1) Place mating marks on the differential companion
flange and flange yoke for reference during reassembly.(2) Remove the differential carrier and propeller shaft
connection.(3) Support the propeller shaft with wire.

Align the mating marks on the flange yoke and the
companion flange to install the propeller shaft.
INSPECTION BEFORE DISASSEMBLYNOJIEAIHold the working base in a vice, and attach the differential
carrier to the working base.
FINAL DRIVE GEAR BACKLASH
With the drive pinion locked in place, measure the final drive
gear backlash with a dial indicator on the drive gear.
NOTEMeasure at four points or more on the circumference of the

MENiNWFOAF
NOTE
The brake pads have wear indicators that contact the brake discd’when the brake pad thickness becomes 2 mm
(.08 in.), and
emit a squealing sound to warn the driver.
1. Check brake pad thickness through caliper body check
port.Limit: 2.0 mm
(.08 in.)
Caution1. When the limit is exceeded, replace the pads at
both sides, and also the brake pads for the wheelson the opposite side at the same time.
2.If there is a significant difference in the thicknesses
of the pads on the left and right sides, check the
sliding condition of the piston, lock pin sleeve and
guide pin sleeve.
2.Remove lock or guide pin. Lift caliper assembly and retain
with wires.
Caution
Do not wipe off the special grease that is on the guide
-pin or allow it to contaminate the guide pin.
3. Remove the following parts from caliper support.

NO7FAAE1. Loosen cap.
2.Confirm that the engine coolant level is up to the filler neck.3. Install a adapter to the water outlet fitting and apply
160
kPa (23 psi) pressure. Hold pressure for tvvo minutes, whilechecking for leakage from the radiator, hose or connec-
tionsCaution
Be sure to completely clean away moisture from the
places checked.When the tester
is removed, be careful not to spill anyengine coolant from
it.
Be careful, when installing and removing the tester andwhen testing, not
to deform the water outlet fitting.
4. If there is leakage, repair or replace the appropriate part.
CAP PRESSURE TESTNO’IFBAG
1. Use a special tool to attach the cap to the tester.
2.Increase the pressure until the indicator of the gauge stops
moving.Limit:
65 kPa (9.2 psi)Standard value:
75-105 kPa (11-15 psi)
3.Replace the cap if the reading does not remain at or abovethe limit.
NOTEBe sure that the cap is clean before testing, since rust or
other foreign material on the cap seal will cause an
improper indication.

AUTO-CRUISE CONTROL SYSTEM INSPECTION
AUTO-CRUISE CONTROL SWITCH CHECK(1) Turn the ignition key to ON.
(2) Check to be sure that the indicator light within the switch
illuminates when the cruise control switch is switched ON.
(Turn the cruise control switch to the “CRUISE” position.)
AUTO-CRUISE CONTROL SETTING CHECK(1) Switch ON the cruise control switch.
(2) Drive at the desired speed within the range of approxi-
mately 40-145 km/h (25-90 mph).
(3) Press the SET button.
(4) Check to be sure that the speed is the desired constant
speed when the switch is released, and also check to be
sure that the auto cruise indicator light (tithin the combina-tion meter) illuminates.
NOTE1(
If the vehicle speed decreases to approximately 15 km/h
(9 mph) below the set speed, because of climbing a hill for
example, the auto-cruise control will be
cancelled.
SPEED-INCREASE SETTING CHECK
(‘1) Set to the desird speed.
(2) Turn the control switch to RESUME position.
(3) Check to be sure that acceleration continues while the
switch is hold, and that when it is released the constant
speed at the time when it was released becomes the
driving speed.
NOTEEven if, during acceleration, the vehicle speed reaches or
exceeds the high limit [approximately 145 km/h (90
mph)], acceleration will continue, however, when the
switch is released, the set speed (“memorized speed”) will
become the high limit of the vehicle speed.
’ ” ,
SPEED REDUCTION SETTING CHECK(1) Set to the desired speed.
(2) Press the SET button.
(3) Check to be sure that deceleration continues while the
switch is pressed, and that when it is released the
constant speed at the time when it was released becomes
the driving speed.
NOTEIWhen the vehicle speed reaches the low limit [approxi-
mately 40 km/h (25 mph)] during deceleration, the auto-
matic speed control will be
cancelled.

cancelledwhen either of the operations below is performed.
@ The brake pedal is depressed.
@ The clutch pedal is depressed.
@I The shift lever is moved to the “N” range. (3) Turn the control switch to RESUME position and release
(RESUME switch
ONdOFF) while driving at a vehicle
speed of approximately 40 km/h (25 mph) or higher.
(4) After switching RESUME switch to OFF, check to be sure
that there is a return to the auto-cruise control speed before
it will be
cancelled and the vehicle will travel at the constant
speed.

ACCELERATOR CABLE, THROTTLE CABLE AND
AUTO-CRUISE CONTROL CABLE INSPECTION
AND ADJUSTMENT(1) Remove the link protector. (Refer to P.14140.)
(2) Check that there are no sharp bends and breaks in the
accelerator cable, throttle cable and auto-cruise control
cable.(3) Turn the ignition switch to the ON position (without starting
the engine) and leave in that condition for approximately 15
seconds.(4) Leave plenty of play in each cable and temporarily install
adjusting nuts A,
B, C and adjusting bolts D.
