2. Apply multi-purpose grease to new front oil seal lip. Install new
front oil seal into gear carrier using Tool.
CAUTION:
• Do not reuse front oil seal.
• Do not incline the new front oil seal when installing.
• Apply multi-purpose grease to the lips of the new front oil
seal.
3. Install new collapsible spacer on drive pinion assembly. And
then install drive pinion assembly into gear carrier.
CAUTION:
• Do not reuse collapsible spacer.
• Do not damage front oil seal.
4. Install a new oil seal/dust shield.
5. Install the companion flange onto the drive pinion while aligning
the matching marks. Then tap the companion flange using suit-
able tool.

6. Apply anti-corrosive oil to the threads of the drive pinion and the
seating surface of the new drive pinion lock nut and new drive
pinion lock nut washer. Then adjust the drive pinion lock nut
tightening torque using suitable tool (A), and check the drive pin-
ion bearing preload torque using Tool (B). Refer to
CAUTION:
• Do not reuse drive pinion lock nut or drive pinion lock nut
washer.
• Apply anti-corrosive oil to the threads of the drive pinion
and the seating surface of the new drive pinion lock nut.
• Adjust the drive pinion lock nut tightening torque to the
lower limit first. Do not exceed the drive pinion lock nut
specified torque.
• If the drive pinion bearing 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 drive pinion bearing preload torque.
• After adjustment, rotate drive pinion back and forth 2 to 3
times to check for unusual noise, rotation malfunction,
and other malfunctions.
Differential Assembly
1. Apply sealant to threads of differential lock position switch.
• Use Genuine Silicone RTV or equivalent. Refer to
GI-21, "Recommended Chemical Products and Seal-
CAUTION:
Remove old sealant adhering to gear carrier and differential lock position switch. Also remove any
moisture, oil, or foreign material adhering to application and gear carrier and differential lock posi-
tion switch.
2. Install differential lock position switch on gear carrier and tighten
differential lock position switch bolts to the specified torque.
3. Apply gear oil to side bearings. Install differential case assembly
with side bearing outer races into gear carrier.
4. Apply multi-purpose grease to new sensor connector.
CAUTION:
Do not reuse sensor connector.

5. Connect differential lock solenoid harness to new sensor con-
nector. Then install new sensor connector to gear carrier and
tighten to the specified torque.
6. Align paint matching mark on side bearing caps with those on
gear carrier and install side bearing caps on gear carrier.
CAUTION:
Do not tighten side bearing cap bolts at this point. This
allows further tightening of side bearing adjusters.
7. Tighten each side bearing adjusters using adjuster tool. Perform
the following adjustments.
• Adjusting backlash of drive gear and drive pinion. Refer to
DLN-271, "Inspection and Adjustment"
.
• Check total preload. Refer to
• Check tooth contact. Refer to
8. Apply a bead of sealant to the mating surface of the carrier
cover as shown.
• Use Genuine Silicone RTV or equivalent. Refer to
"Recommended Chemical Products and Sealants"
.
CAUTION:
Remove any old sealant adhering to the mating surfaces.
Also remove any moisture, oil, or foreign material adhering
to the application and mating surfaces.
9. Install the carrier cover to the gear carrier. Tighten the bolts to
the specified torque.
