4. If tooth contact is improperly adjusted, follow the procedure
below to adjust the pinion height (dimension X).
 If 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 to RFD-38, "
Inspection and Adjustment".
 If 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 to RFD-38, "
Inspection and Adjustment".
Backlash
1. Remove rear cover. Refer to "Differential Assembly".
2. Fit a dial indicator to the drive gear face to measure the back-
lash.
 If the backlash is outside of the specified value, change the thick- ness of side bearing adjusting washer.
CAUTION:

Backlash: 0.10 - 0.15 mm (0.0039 - 0.0059 in)
When the backlash is large: Make drive gear back side adjusting washer thicker,
and drive gear tooth side adjusting washer thinner by
the same amount. Refer to RFD-38, "
Inspection and
Adjustment".
When the backlash is small: Make drive gear back side adjusting washer thinner,
and drive gear tooth side ad justing washer thicker by
the same amount. Refer to RFD-38, "

Never change the total amount of washers as it will change the bearing preload.
Companion Flange Runout
1. Fit a test indicator to the inner side of companion flange (socket
diameter).
2. Rotate companion flange to check for runout.
3. If the runout value is outside t he runout limit, follow the proce-
dure below to adjust.
a. Check for runout while changing the phase between companion flange and drive pinion by 90 ° step, and search for the position
where the runout is the minimum.
b. If the runout value is still outside of the limit after the phase has been changed, possible cause will be an assembly malfunction of drive pinion and pinion bearing and
malfunction of pinion bearing. Check for these items and repair if necessary.
c. If the runout value is still outside of the limit after the check and repair, replace companion flange.
DISASSEMBLY
Differential Assembly
1. Drain gear oil, if necessary.
2. Remove side flange.
3. Remove rear cover mounting bolts.
4. Remove rear cover to insert the seal cutter between gear carrier and rear cover.
CAUTION:
 Be careful not to damage the mating surface.
 Never insert flat-bladed screwdriver, this way damage the
mating surface.
5. Using two 45 mm (1.77 in) spacers, mount carrier on the attach- ment.Runout limit: 0.08 mm (0.0031 in)

6. For proper reinstallation, paint matching marks on one side of the bearing cap.
CAUTION:
 For matching marks, use paint. Never damage bearingcaps and gear carrier.
 Bearing caps are line-board during manufacture. The
matching marks are used to re install them in their original
positions.
7. Remove bearing caps.
8. Lift differential case assembly out with a suitable tool.
 Keep side bearing outer races together with inner race. Do notmix them up.
Also, keep side bearing adjusting washers together with bear-
ings.

Content Conditions and Measures
Hypoid gear  If the gear teeth do not mesh or line-up correctly, determine the cause and adjust or replace as nec-
essary.
 If the gears are worn, cracked, damaged, pitted or chipped (by friction) noticeably, replace with new drive gear and drive pinion as a set.
Bearing  If any chipped (by friction), pitted, worn, rusted or scratched mark, or unusual noise from the bearing
is observed, replace as a bearing assembly (as a new set).
Side gear and Pinion mate
gear  If any cracks or damage on the surface of the tooth is found, replace.
 If any worn or chipped mark on the contact sides of the thrust washer is found, replace.
Side gear thrust washer and
pinion mate thrust washer  If it is chipped (by friction), damaged, or unusually worn, replace.
Oil seal  Whenever disassembled, replace.
 If wear, deterioration of adherence (sealing force lips), or damage is detected on the lips, replace them.
Differential case  If any wear or crack on the contact sides of the differential case is found, replace.
Companion flange  If any chipped mark (about 0.1 mm, 0.004 in) or other damage on the contact sides of the lips of the
companion flange is found, replace.

Differential Side Gear Clearance
 Assemble the differential parts if they are disassembled. Refer to "Differential Assembly".
1. Place differential case straight up so that side gear to be mea-
sured comes upward.
2. Using feeler gauge, measure the clearance between side gear back and differential case at 3 different points, while rotating
side gear. Average the 3 readings, and then measure the clear-
ance of the other side as well.
CAUTION:
To prevent side gear from tilting, insert feeler gauges with
the same thickness from both sides.
3. If the back clearance is outside t he specification, use a thicker/
thinner side gear thrust washer to adjust. Refer to RFD-38,
"Inspection and Adjustment".
CAUTION:
Select a side gear thrust washer for right and left individually.
Side Bearing Preload
 Selecting carrier side bearing adjusting washers is required for successful completion of this procedure.
1. Make sure all parts are clean. Also, make sure the bearings are
well lubricated with gear oil.
2. Place the differential case, with side bearings and bearing races installed, into gear carrier.
PDIA0460E
Side gear back clearance specification:
0.2 mm (0.008 in) or less.
(Each gear should rotate smoothly without excessive
resistance during differential motion.)
When the back clearance is large:
Use a thicker thrust washer.
When the back clearance is small: Use a thinner thrust washer.

4. Install bearing caps in their correct locations and tighten bearing cap mounting bolts to the specified torque. Refer to "COMPO-
NENTS".
5. Turn the carrier several times to seat the bearings.
6. Measure the turning torque of the carrier at the drive gear mounting bolts with a spring gauge.
7. If the turning torque is outside the specification, use a thicker/ thinner side bearing adjusting washer to adjust. Refer to RFD-
38, "Inspection and Adjustment".
CAUTION:
Select a side bearing adjust ing washer for right and left
individually.
8. Record the total amount of washer thickness required for the correct carrier side bearing preload.

1. Make sure all parts are clean and that the bearings are well lubricated.
2. Assemble the pinion gear beari ngs into the differential shim
selector tool.
 Pinion front bearing; make sure the J-34309-3 pinion front
bearing seat is secured tightly against the J-34309-2 gauge
anvil. Then turn the pinion front bearing pilot, J-34309-5, to
secure the bearing in its proper position.
 Pinion rear bearing; the pinion rear bearing pilot, J-34309-8,
is used to center the pinion rear bearing only. The pinion rear
bearing locking seat, J-34309-4, is used to lock the bearing to
the assembly.
 Installation of J-34309-9 and J-34309-16; place a suitable
2.5 mm (0.098 in) thick plain washer between J-34309-9 and
J-34309-16. Both surfaces of J-34309-9 and J-34309-16 must
be parallel with a clearance of 2.5 mm (0.098 in).
3. Install the pinion rear bearing inner race into gear carrier. Then place the pinion preload shim selector tool, J-34309-1, gauge
screw assembly.
4. Assemble the pinion front bearing inner race and the J-34309-2 gauge anvil. Assemble them together with the J-34309-1 gauge
screw in gear carrier. Make sure that the pinion height gauge
plate, J-34309-16, will turn a full 360 degrees. Tighten the two
sections together by hand.
5. Turn the assembly several times to seat the bearings. Tool number : — (J-34309)
