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" .
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)
Drive pinion lock nut tightening torque: 147 - 323 N·m (15 - 32 kg-m, 109 - 238 ft-lb)

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-27, "
Side
Bearing Preload" .
13. Insert selected left and right side bearing adjusting washers in place between side bearings and gear carrier.
14. Align matching marks on bearing cap with that on gear carrier.

16. Using the drift, drive side oil seals until it becomes flush with the case end.
CAUTION:

Do not reuse oil seal.

When installing, do not incline oil seal.

Apply multi-purpose grease onto oil seal lips, and gear
oil onto the circumference of oil seal.
17. Check and adjust drive gear runout, tooth contact, drive gear to drive pinion backlash, and total preload torque. Refer to RFD-
19, "Drive Gear Runout" , RFD-20, "Tooth Contact" , RFD-21,
"Backlash" , RFD-19, "Total Preload Torque" .
Recheck above items. Readjust the above description, if necessary.
18. Apply sealant to mating surface of rear cover.

Use Genuine Silicone RTV or equivalent. Refer to GI-48,
"RECOMMENDED CHEMICAL PRODUCTS AND SEAL-
ANTS" .
CAUTION:
Remove old sealant adhering to mounting surfaces. Also
remove any moisture, oil, or foreign material adhering to
application and mounting surfaces.
19. Install rear cover on gear carrier and tighten mounting bolts with the specified torque. Refer to RFD-18, "
COMPONENTS" .
20. Install side flange with the following procedure.
a. Attach the protector to side oil seal.
b. After the side flange is inserted and the serrated part of side gear has engaged the serrated part of flange, remove the pro-
tector.
c. Put a suitable drift on the center of side flange, then drive it until sound changes.
NOTE:
When installation is completed, driving sound of the side flange
turns into a sound which seems to affect the whole final drive.
d. Confirm that the dimension of the side flange installation (Mea- surement A) in the figure comes into the following. Tool number : KV38100200 (J-26233)
