1. Apply multi-purpose grease to the lips of the new front oil seal.
Then drive the new front oil seal in evenly until it becomes flush
with the 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 and differential
gear oil to the circumference of the new front oil seal.
2. Install a new oil seal/dust shield.
3. Install the companion flange to the drive pinion while aligning the matching marks.
4. 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 total pre-
load torque using Tool (B).
• The total preload torque should be within the total preload
torque specification. When not replacing the collapsible
spacer, it should also be equal to the measurement taken dur-
ing removal plus an additional 0.56 N·m (0.06 kg-m, 5 in-lb).
• If the total preload torque is low, tighten the drive pinion lock
nut in 6.8 N·m (0.69 kg-m, 60 in-lb) increments until the total
preload torque is met.
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. Refer to
.
• Do not loosen drive pinion lock nut to adjust the total preload torque. If the total preload torque
exceeds the specifications, replace the collapsible spacer and tighten it again to adjust. Refer to
DLN-261, "Disassembly and Assembly"
• After adjustment, rotate drive pinion back and forth 2 to 3 times to check for unusual noise, rota-
tion malfunction, and other malfunctions.
5. Installation of the remaining components is in the reverse order of removal.
CAUTION:
Check the differential gear oil level after installation. Refer to
DLN-250, "Changing Differential Gear
.

Also remove any moisture, oil, or foreign material adhering
to the application and mating surfaces.
2. Install the carrier cover to the gear carrier. Tighten the bolts to
the specified torque. Refer to
3. Connect the parking brake cable and brake tube to the carrier
cover.
4. Fill the rear final drive assembly with recommended differential gear oil. Refer to
.
