15) Re-check crown gear-to-pinion backlash.
Backlash:
0.10—0.20 mm (0.0039—0.0079 in)
G3M1048
16) Check the crown gear runout on its back surface, and
make sure pinion and crown gear rotate smoothly.
Limit of runout:
0.05 mm (0.0020 in)
17) Checking and adjusting tooth contact of crown gear
(1) Apply an even coat of red lead on both sides of
three or four teeth on the crown gear. Check the con-
tact pattern after rotating crown gear several revolu-
tions back and forth until a definite contact pattern
appears on the crown gear.
(2) When the contact pattern is incorrect, readjust
according to the instructions given in“TOOTH CON-
TACT PATTERN”.
NOTE:
Be sure to wipe off red lead completely after adjustment is
completed.
18) If proper tooth contact is not obtained, once again
adjust the drive pinion height and the differential side bear-
ing preload (mentioned above) and the hypoid gear back-
lash.

TOOTH CONTACT PATTERN
Condition Contact pattern Adjustment
Correct tooth contact
Tooth contact pattern slightly shifted
towards toe under no load rotation.
(When loaded, contact pattern moves
toward heel.)

Face contact
Backlash is too large.This may cause noise and chipping at
tooth ends.
B3M0319
Increase thickness of drive pinion height
adjusting shim in order to bring drive
pinion closer to crown gear center.
B3M0323
Flank contact
Backlash is too small.This may cause noise and stepped wear
on surfaces.
B3M0320
Reduce thickness of drive pinion height
adjusting shim in order to move drive
pinion away from crown gear.

Toe contact
Contact area is small.This may cause chipping at toe ends.

If toe-in or front camber tolerance exceeds specifications,
adjust toe-in and camber to the specification.

The other items indicated in the specification table can-
not be adjusted. If the other items exceeds specifications,
check suspension parts and joint portions of body suspen-
sion parts for deformities; and replace with new ones as
required.

1. WHEEL ARCH HEIGHT
1) Adjust tire pressure to specifications.
2) Set vehicle under“curb weight”conditions. (Empty lug-
gage compartment, install spare tire, jack, service tools,
and top up fuel tank.)
3) Set steering wheel in a wheel-forward position.
4) Suspend thread from wheel arch (point“A”in figure
below) to determine a point directly above center of
spindle.
5) Measure distance between measuring point and center
of spindle.

2. CAMBER AND CASTER

Inspection
1) Place front wheel on turning radius gauge. Make sure
ground contacting surfaces of front and rear wheels are set
at the same height.
2) Set ST into the center of the wheel, and then install the
wheel alignment gauge.
ST 927380000 ADAPTER
NOTE:
Refer to the“SPECIFICATIONS AND SERVICE DATA”for
the camber and caster values.

Front camber adjustment
1) Loosen two self-locking nuts located at lower front por-
tion of strut.
CAUTION:

When adjusting bolt needs to be loosened or
tightened, hold its head with a wrench and turn self-
locking nut.

Discard loosened self-locking nut and replace with a
new one.

2) Turn camber adjusting bolt so that camber is set at the
specification.
NOTE:
Moving the adjusting bolt by one scale graduation changes
camber by approximately 0°10′.

2) Mark rear sides of left and right tires at height corre-
sponding to center of spindles and measure distance“B”
between marks.
3) Move vehicle forward so that marks line up with front
sides at height corresponding to center of spindles.
4) Measure distance“A”between left and right marks.

Adjustment
1) Loosen the left and right side steering tie-rods lock nuts.
2) Turn the left and right tie rods equal amounts until the
toe-in is at the specification.
Both the left and right tie-rods are right-hand threaded. To
increase toe-in, turn both tie-rods clockwise equal amounts
(as viewed from the inside of the vehicle).
3) Tighten tie-rod lock nut.
Tightening torque:
83±5 N⋅m (8.5±0.5 kg-m, 61.5±3.6 ft-lb)
CAUTION:
Correct tie-rod boot, if it is twisted.
NOTE:
Check the left and right wheel steering angle is within
specifications.
