4. Install bearing caps in their correct locations and tighten bearing
cap mounting bolts to the specified torque. Refer to RFD-18,
"COMPONENTS" .
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, "Side Bearing Adjusting Washer" .
CAUTION:
Select a side bearing adjusting washer for right and left
individually.
8. Record the total amount of washer thickness required for the correct carrier side bearing preload.
Pinion Gear Height
1. Make sure all parts are clean and that the bearings are well lubricated.
2. Assemble the pinion gear bearings 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.
6. Measure the turning torque at the end of the J-34309-2 gauge anvil using preload gauge.

7. Place the J-34309-11 “R200A” pinion height adapter onto the
gauge plate and tighten it by hand.
CAUTION:
Make sure all machined surfaces are clean.
8. Position the side bearing discs, J-25269-4, and arbor firmly into the side bearing bores. Install the bearing caps and tighten bear-
ing cap mounting bolts to the specified torque. Refer to RFD-18,
"COMPONENTS" .
9. Select the correct standard pinion height adjusting washer thick- ness. Select by using a standard gauge of 3 mm (0.12 in) and
your J-34309-101 feeler gauge. Measure the distance between
the J-34309-11 pinion height adapter including the standard
gauge and the arbor.
10. Write down exact measurement (the value of feeler gauge).
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 the following chart to determine
the correct pinion height washer.

10. Apply anti-corrosion oil to the thread and seat of drive pinion
lock nut, and temporarily tighten drive pinion lock nut to drive
pinion.
CAUTION:
Do not reuse drive pinion lock nut.
11. Adjust to the drive pinion lock nut tightening torque and pinion bearing preload torque.
CAUTION:

Adjust to the lower limit of the drive pinion lock nut tight-
ening torque first.

If the preload torque exceeds the specified value, replace
collapsible spacer and tighten it again to adjust. Do not
loosen drive pinion lock nut to adjust the preload torque.

After adjustment, rotate drive pinion back and forth 2 to 3
times to check for unusual noise, rotation malfunction,
and other malfunctions.
12. Install differential case assembly. Refer to RFD-33, "
Differential Assembly" .
CAUTION:
Do not install rear cover yet.
13. Check and adjust drive gear runout, tooth contact, drive gear to drive pinion backlash, and companion flange runout. Refer to RFD-19, "
Drive Gear Runout" , RFD-20, "Tooth Contact" , RFD-21, "Backlash" ,
RFD-22, "
Companion Flange Runout" .
Recheck above items. Readjust the above description, if necessary.
14. Check total preload torque. Refer to RFD-19, "
Total Preload Torque" .
15. Install rear cover. Refer to RFD-33, "
Differential Assembly" .

1. Install side gear thrust washers with the same thickness as the
ones installed prior to disassembly or reinstall the old ones on
the side gears. Tool number A: ST3127S000 (J-25765-A)
