4. If tooth contact is improperly adjusted, follow the procedure
below to adjust the pinion height (dimension X).
lIf the tooth contact is near the face (face contact), or near the
heel (heel contact), thicken pinion height adjusting washers to
move drive pinion closer to drive gear.
Refer toFFD-38, "
Pinion Height Adjusting Washer".
lIf the tooth contact is near the flank (flank contact), or near the
toe (toe contact), thin pinion height adjusting washers to move
drive pinion farther from drive gear.
Refer toFFD-38, "
Pinion Height Adjusting Washer".
Backlash
1. Remove rear cover. Refer toFFD-22, "Differential Assembly".
2. Fit a dial indicator to the drive gear face to measure the back-
lash.
lIf the backlash is outside of the specified value, change the
thickness of side bearing adjusting washer.
CAUTION:
Do not change the total amount of washers as it will change the bearing preload.

Backlash: 0.10 - 0.15 mm (0.0039 - 0.0059 in)
When the backlash is greater than specification:
Make drive gear back side adjusting washer thicker,
and drive gear tooth side adjusting washer thinner by
the same amount. Refer toFFD-38, "
Side Bearing
Adjusting Washer".
When the backlash is less than specification:
Make drive gear back side adjusting washer thinner,
and drive gear tooth side adjusting washer thicker by
the same amount. Refer toFFD-38, "
Side Bearing

4. Put matching mark on the end of drive pinion. The matching
mark should be in line with the matching mark A on companion
flange.
CAUTION:
Use paint for matching mark. Do not damage companion
flange or drive pinion.
NOTE:
The matching mark A on the final drive companion flange indi-
cates the maximum vertical runout position.
When replacing companion flange, matching mark is not neces-
sary.
5. Remove companion flange using suitable tool.
6. Press drive pinion assembly out of gear carrier. (Together with
collapsible spacer.)
CAUTION:
Do not drop drive pinion assembly.
7. Remove pinion rear bearing inner race and drive pinion height
adjusting washer using Tool.
8. Remove front oil seal using suitable tool.
CAUTION:
Do not damage gear carrier.
9. Remove pinion front bearing inner race.
10. Remove collapsible spacer.

Pinion Gear Height
If the hypoid gear set has been replaced, select the pinion height adjusting washer.
1. Use the formula below to calculate pinion height adjusting
washer thickness.
2. Select the proper pinion height adjusting washer. Refer toFFD-38, "
Pinion Height Adjusting Washer".
If you cannot find the desired thickness of washer, use washer with thickness closest to the calculated
value.

1. Install front and rear bearing outer races using Tools.
CAUTION:
lFirst tap the bearing outer race until it becomes flat to the
gear carrier.
lDo not reuse pinion front and rear bearing outer race.Washer selection equation:

Press pinion rear bearing inner race to it using Tool.
CAUTION:
lPay attention to the direction of pinion height adjusting
washer. (Assemble as shown in the figure.)
lDo not reuse pinion rear bearing inner race.
4. After checking and adjusting the tooth contact and backlash of
the hypoid gear following the procedure below.
a. Apply gear oil to the drive pinon rear bearing, and assemble the
drive pinion to the gear carrier.
CAUTION:
Do not assemble a collapsible spacer.
b. Apply gear oil to drive pinon front bearing, and assemble pinion front bearing inner race to drive pinion.
CAUTION:

Front Suspension PartsEES002KM
Check front suspension parts for excessive play, cracks, wear and
other damage.
lShake each front wheel to check for excessive play.
If looseness is noted, inspect wheel bearing end play, then
check ball joint end play. Refer toFSU-15, "
Inspection".
lMake sure that the cotter pin is inserted in drive shaft end (4WD
models only).
lRetighten all nuts and bolts to the specified torque.
lCheck shock absorber for oil leakage and other damage.
lCheck suspension ball joint for grease leakage and ball joint
dust cover for cracks and other damage.
Front Wheel AlignmentEES002KN
PRELIMINARY INSPECTION
WARNING:
Always adjust the alignment with the vehicle on a flat surface.
NOTE:
If alignment is out of specification, inspect and replace any damaged or worn rear suspension parts before
making any adjustments.
1. Check and adjust the wheel alignment with the vehicle under unladen conditions. “Unladen conditions”
means that the fuel, coolant, and lubricant are full; and that the spare tire, jack, hand tools and mats are in
their designated positions.
2. Check the tires for incorrect air pressure and excessive wear.
3. Check the wheels for run out and damage. Refer toWT-3, "
Inspection".
4. Check the wheel bearing axial end play. Refer toFA X - 5 , "
WHEEL BEARING INSPECTION".
5. Check the shock absorbers for leaks or damage.
6. Check each mounting point of the suspension components for any excessive looseness or damage.
7. Check each link, arm, and the rear suspension member for any damage.
8. Check the vehicle height. Refer toFSU-21, "
Wheelarch Height (Unladen*1)". Suspension component torques : Refer toFSU-6,
"Components".SMA525A
