TOOTH CONTACT INSPECTION
Checking gear tooth contact pattern is necessary to verify correct relationship between drive gear and drive
pinion.
Hypoid gears which are not positioned in proper arrangement may be noisy and/or have a short life. Check
gear tooth contact pattern to obtain the best contact for low noise and long life.
1. Thoroughly clean drive gear and drive pinion teeth.
2. Lightly apply a mixture of powdered ferric oxide and oil or the
equivalent. Apply it to 3 or 4 teeth on the drive side of drive
gear.
3. Hold companion flange steady by hand and rotate the drive gear
in both directions.
4. Check the tooth contact on both sides (drive side and coast
side).
NOTE:
Refer to FFD-31, "
TOOTH CONTACT PATTERN AND HEIGHT
ADJUSTING WASHER SELECTION" for detail of tooth contact
pattern.

2. If there is heel contact or face contact, increase point height
adjusting washer in order to bring drive pinion close to drive
gear.
3. If there is toe contact or flank contact, decrease pinion adjusting
washer in order to make drive pinion go away from drive gear.
4. Set dial indicator to the drive gear face and measure the bak-
clash.

If the measured value out of standard, adjust the backlash by
replacing the side bearing adjusting shim (carrier case side).
–If backlash too large, decrease side bearing adjusting shim
thickness.
–If backlash too small, increase side bearing adjusting shim
thickness.

TOTAL PRELOAD INSPECTION
1. Turn companion flange in both directions 20 times or more to set
bearing rollers, then check total preload with special service tool.

If the preload value is out of standard, adjust by changing side
bearing adjusting shim thickness (side retainer side).
–If preload value too large, increase the side bearing adjusting
shim thickness.
–If preload value too small, decrease the side bearing adjusting shim thickness.
DRIVE PINION PRELOAD ADJUSTMENT
Removal of differential case assembly
1. Unfasten the retainer tab using a flat blade screwdriver.
2. Remove the retainer by pulling it and tapping carrier case using a plastic hammer.
3. Remove the differential case assembly from the carrier case.
CAUTION:
Be careful not to damage the carrier cover mating surface.
Removal of drive pinon assembly
1. Hold the companion flange using cam sprocket wrench or flange
wrench, remove the drive pinion lock nut.
2. Remove the companion flange using puller.
3. Temporarily install drive pinion lock nut.
CAUTION:
Avoid damaging drive pinion threads, install the drive pinion lock nut unit it flash with drive pinion
end.
4. Remove the drive pinion from the carrier case using a copper hammer.
Preload Adjustment
1. Install drive pinion adjusting washer and drive pinion bearing adjusting washer onto the drive pinion, then
install drive pinion into the carrier case.
CAUTION:
Install the removed pinion height adjusting washer and drive pinion bearing adjusting washer or
same thickness washers to drive pinion.
2. Apply gear oil to the bearing portion.
3. Install drive pinion and drive pinion bearing into the carrier case.
4. Install the companion flange without installing oil seal.
5. Apply oil to drive pinion nut threads and seating surface, then temporarily install it.
6. Turn companion flange several times to seat the bearing.
7. Tighten the drive pinion nut while measuring preload using preload gauge.
8. Select drive pinion adjusting washer and drive pinion bearing adjusting washer so that standard preload is
obtain when the drive pinion nut is tightened to specified torque.Tool number : ST3127S000 (see J25765-A)

On-Vehicle Inspection and ServiceAES000N3
Make sure the mounting conditions (looseness, back lash) of each component and component statues (wear,
damage) are normal.
INSPECTION OF TRANSVERSE LINK BALL JOINT END PLAY
1. Set front wheels in a straight-ahead position. Do not depress brake pedal.
2. Measure axial end play by installing and moving up/down between transverse link and steering knuckle
with an iron pry bar or something similar.
CAUTION:
Be careful not to damage ball joint boot.
STRUT INSPECTION
Check strut for oil leakage, damage and replace if necessary. Refer to FSU-11, "COIL SPRING AND STRUT" .
Wheel Alignment InspectionAES000N4
DESCRIPTION
Measure wheel alignment under unladen conditions.
NOTE:
Unladen conditions mean that fuel, engine coolant, and lubricant are full. Spare tire, jack, hand tools and mats
are designated positions.
PRELIMINARY CHECK
1. Check tires for improper air pressure and wear.
2. Check road wheels for runout.
3. Check wheel bearing axial end play.
4. Check transverse link ball joint axial end play.
5. Check strut operation.
6. Check each mounting part of axle and suspension for looseness and deformation.
7. Check each link, rod and member for cracks, deformation and other damage.
8. Check vehicle posture.
INSPECTION OF CAMBER, CASTER AND KINGPIN INCLINATION ANGLES

Camber, caster, kingpin inclination angles cannot be adjusted.

Before inspection, mount front wheels onto turning radius gauge. Mount rear wheels onto a stand that has
same height so vehicle will remain horizontal.
Using a CCK Gauge
Install CCK gauge attachment (SST: KV991040S0) as following procedure in wheel, then measure wheel
alignment.
1. Remove wheel nuts (3), and install a guide bolt to hub bolt.
2. Screw adapter into plate body until it contacts body tightly.
3. Screw center plate into plate.
4. Insert plate on guide bolt. Put spring in, and then evenly screw
both guide bolt nut. When fastening guide bolt nut, do not com-
pletely compress spring.Axial end play : 0 mm (0 in)

5. Place the dent of alignment gauge onto the projection of center
plate and tightly contact them to measure.
CAUTION:

If camber, caster, or kingpin inclination angle is outside
the standard, check front suspension parts for wear and
damage, and replace suspect parts if necessary.

King pin inclination angle is reference value, no inspec-
tion is required.
Toe-In Inspection
Measure 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 vehicle before push-
ing it.
1. Bounce front of vehicle up and down to stabilize the posture.
2. Push vehicle straight ahead about 5 m (16 ft).
3. Put a mark on base line of the tread (rear side) of both tires at
the same height of hub center. These are measuring points.
4. Measure distance “A” (rear side).
5. Push vehicle slowly ahead to rotate wheels 180 degrees (1/2
turn).
If 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 “B” (front side).Camber, caster, kingpin inclination angles:
