Precautions
PRECAUTIONSNJSU0001+When installing rubber parts, final tightening must be car-
ried out under unladen condition* with tires on ground.
Oil will shorten the life of rubber bushes. Be sure to wipe
off any spilled oil.
*: Fuel, radiator coolant and engine oil full. Spare tire, jack,
hand tools and mats in designated positions.
+After installing removed suspension parts, check wheel
alignment and adjust if necessary.
+Use flare nut wrench when removing or installing brake
tubes.
+Always torque brake lines when installing.
+Lock nuts are unreusable parts; always use new ones.
When replacing, do not wipe the oil off the new lock nut
before tightening.

FRONT SUSPENSION PARTSNJSU0006Check front axle and front suspension parts for excessive play,
cracks, wear or other damage.
+Shake each front wheel to check for excessive play.
+Make sure that cotter pin is inserted.
+Retighten all axle and suspension nuts and bolts to the speci-
fied torque.
Tightening torque:
Refer to ªFRONT SUSPENSIONº, SU-5.
SFA392B
+Check strut (shock absorber) for oil leakage or other damage.
+Check suspension ball joint for grease leakage and ball joint
dust cover for cracks or other damage.
If ball joint dust cover is cracked or damaged, replace trans-
verse link.
SFA818AA
+Check spring height from top of wheelarch to the ground.
a) Vehicle must be unladen*, parked on a level surface, and tires
checked for proper inflation and wear (tread wear indicator
must not be showing).
*: Fuel, radiator coolant and engine oil full. Spare tire, jack,
hand tools and mats in designated positions.
b) Bounce vehicle up and down several times before measuring.
Standard height: Refer to SDS, SU-15.
c) Spring height is not adjustable. If out of specification, check for
worn springs or suspension parts.
SSU031
+Check suspension ball joint end play.
a) Jack up front of vehicle and set the stands.
b) Clamp dial indicator onto transverse link and place indicator tip
on lower edge of brake caliper.
c) Make sure front wheels are straight and brake pedal is
depressed.
d) Place a pry bar between transverse link and inner rim of road
wheel.
e) While raising and releasing pry bar, observe maximum dial
indicator value.
Vertical end play: 0 mm (0 in)
f) If ball joint movement is beyond specifications, remove and
replace it.

BALANCING WHEELSNJSU0042Preliminary InspectionNJSU0042S011. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage.
If deformed, remove wheel and check wheel runout.
a. Remove tire from wheel and mount wheel on a tire balance
machine.
b. Set dial indicator as shown in the illustration.
Wheel runout (Dial indicator value):
Refer to SDS, SU-15.
3. Check front wheel bearings for looseness.
4. Check front suspension for looseness.
5. Check steering linkage for looseness.
6. Check that front shock absorbers work properly.
7. Check vehicle posture (Unladen).
SMA829C
TIRE ROTATIONNJSU0043+Do not include the T-type spare tire when rotating the tires.
Wheel nuts:
: 98 - 118 N´m (10.0 - 12.0 kg-m, 72 - 87 ft-lb)
FRONT WHEEL ALIGNMENTNJSU0045Before checking front wheel alignment, be sure to make a prelimi-
nary inspection (Unladen*).
*: Fuel, radiator coolant and engine oil full. Spare tire, jack, hand
tools and mats in designated positions.
SRA096A
Camber, Caster and Kingpin InclinationNJSU0045S01Camber, caster and kingpin inclination are preset at factory
and cannot be adjusted.
1. Measure camber, caster and kingpin inclination of both right
and left wheels with a suitable alignment gauge.
Camber, caster and kingpin inclination:
Refer to SDS, SU-14.
2. If camber, caster or kingpin inclination is not within
specification, inspect front suspension parts. Replace dam-
aged or worn out parts.

Toe-inNJSU0045S02Measure toe-in using the following procedure.
WARNING:
+Always perform the following procedure on a flat surface.
+Make sure that no person is in front of the vehicle before
pushing it.
1. Bounce front of vehicle up and down to stabilize the posture.
2. Push the vehicle straight ahead about 5 m (16 ft).
3. Put a mark on base line of tread (rear side) of both tires at the
same height as hub center. These are measuring points.
SFA234AC
4. Measure distance ªAº (rear side).
5. Push the vehicle slowly ahead to rotate the wheels 180
degrees (1/2 turn).
If the wheels have rotated more than 180 degrees (1/2 turn), try
the above procedure again from the beginning. Never push
vehicle backward.
6. Measure distance ªBº (front side).
Total toe-in:
Refer to SDS, SU-14.
SFA486A
7. Adjust toe-in by varying the length of steering tie-rods.
a. Loosen lock nuts.
b. Adjust toe-in by screwing tie-rods in and out.
Standard length ªLº:
Refer to ST-30, ªSDSº.
c. Tighten lock nuts to specified torque.
Lock nut tightening torque:
Refer to ST-15, ªPOWER STEERING GEAR AND
LINKAGEº.
SFA439BA
Front Wheel Turning AngleNJSU0045S031. Set wheels in straight-ahead position. Then move vehicle for-
ward until front wheels rest on turning radius gauge properly.
2. Rotate steering wheel all the way right and left; measure turn-
ing angle.
Do not hold the steering wheel on full lock for more than
15 seconds.
Wheel turning angle (Full turn):
Refer to SDS, SU-14.
