4. Install bearing caps in their correct locations and tighten bearing
cap mounting bolts to the specified torque. Refer to RFD-16,
"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-
37, "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.

10. Apply gear 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-32, "
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-17, "
Drive Gear Runout" , RFD-18, "Tooth Contact" , RFD-19, "Backlash" ,
RFD-20, "
Companion Flange Runout" .
Recheck above items. Readjust the above description, if necessary.
14. Check total preload torque. Refer to RFD-17, "
Total Preload Torque" .
15. Install rear cover. Refer to RFD-32, "
Differential Assembly" .
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.
2. Install side gears and thrust washers into differential case. CAUTION:
Make sure that the circular clip is installed to side gears.
3. Align 2 pinion mate gears in diagonally opposite positions, then rotate and install them into differential case after installing thrust
washer to pinion mate gear. Tool number A: KV40104000 ( — )
B: ST3127S000 (J-25765-A)
Drive pinion lock nut tightening torque: 147 - 323 N·m (15 - 32 kg-m, 109 - 238 ft-lb)
Drive pinion bearing preload: 2.65 - 3.23 N·m (0.27 - 0.32 kg-m, 24 - 28 in-lb)

4. Align the lock pin holes on differential case with shaft, and install
pinion mate shaft.
5. Measure side gear end play. If necessary, select the appropriate side gear thrust washers. Refer to RFD-25, "
Differential Side
Gear Clearance" .
6. Drive a lock pin into pinion mate shaft, using a punch. Make sure lock pin is flush with differential case.
CAUTION:
Do not reuse lock pin.
7. Align the matching mark of differential case with the mark of drive gear, then place drive gear.
8. Apply thread locking sealant into the thread hole of drive gear.

Use Genuine High Strength Thread Locking Sealant or
equivalent. Refer to GI-48, "
RECOMMENDED CHEMICAL
PRODUCTS AND SEALANTS" .
CAUTION:
Drive gear back and threaded holes shall be cleaned and
degreased sufficiently.
9. Install drive gear on the mounting bolts, and then tighten to the specified torque. Refer to RFD-16, "
COMPONENTS" .
CAUTION:

Tighten bolts in a crisscross fashion.

After tightening the bolt to the specified torque, tighten
the bolts additionally by turning the bolts 31 to 36
degrees.

and the base.
CAUTION:
Do not reuse side bearing inner race.
11. Install differential case assembly with side bearing outer races into gear carrier.
12. Measure side bearing preload. If necessary, select the appropri- ate side bearing adjusting washers. Refer to RFD-26, "
