9. If the turning torque is outside the specification, use a thicker/ thinner side bearing adjusting shim to adjust. Refer to FFD-39,
"Inspection and Adjustment".
10. Record the total amount of shim thickness required for the cor- rect carrier side bearing preload.
Pinion Gear Height
If the hypoid gear set has been replaced, se lect 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 to FFD-39, "
Inspection and Adjustment".
If impossible find the desired thickness of washer, us e washer with thickness closest to the calculated
value.
Pinion Bearing Preload
 Assemble the drive pinion parts if they are disassembled. Refer to "Drive Pinion Assembly".
1. Make sure all parts are clean. Also, make sure the bearings are well lubricated with gear oil.
2. Install companion flange (1). NOTE:
When reusing drive pinion, align the matching mark (B) of drive
pinion with the matching mark (A) of companion flange, and then
install companion flange (1).If the turning torque is l
ess than the specified range:
Decrease the side bearing adjusting shim thickness.
If the turning torque is gr eater than the specification:
Increase the side bearing adjusting shim thickness.

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, "

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.

3. Insert left and right original side bearing adjusting washers inplace between side bearings and gear carrier.
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.

11. Correct the pinion height washer size by referring to the “pinion head number”.
There are two numbers painted on the drive pinion. The first
one refers to the drive pinion and drive gear as a matched
set. This number should be the same as the number on the
drive gear. The second number is the “pinion head height
number”. It refers to the ideal pinion height from standard
for quietest operation. Use th e following chart to determine
the correct pinion height washer.
12. Select the correct pinion height adjusting washer. Refer to RFD-38, "
Inspection and Adjustment".
13. Remove the J-34309 differential shim selector tool from the final drive housing. Then disassemble to retrieve the pinion bearings.
