4. Align the lock pin hole on the differential case with the lock pin
hole on the pinion mate shaft, and install the pinion mate shaft.
5. Measure the side gear end play. If necessary, select the appro-
priate side gear thrust washers. Refer to
6. Drive a new lock pin into the pinion mate shaft until it is flush
with the differential case using suitable tool.
CAUTION:
Do not reuse lock pin.
7. Align the matching mark of the differential case with the mark of
the drive gear, then place the drive gear onto the differential
case.
8. Apply thread locking sealant into the threaded holes of the drive
gear and install the bolts.
• Use Genuine Medium Strength Thread Locking Sealant or
equivalent. Refer to
GI-14, "Recommended Chemical Prod-
CAUTION:
Make sure the drive gear back and threaded holes are
clean.
9. Tighten the drive gear bolts to the specified torque. Refer to
. After tightening the drive gear bolts
to the specified torque, tighten an additional 34
°
using Tool.
CAUTION:
• Always use Tool. Avoid tightening based on visual check
alone.
• Tighten drive gear bolts in a crisscross pattern.

DLN-457, "Removal and Installa-
Side Flange
1. Apply multi-purpose grease to the lips of the new side oil seal.
Then drive the new side oil seal in evenly until it becomes flush
with the gear carrier using Tool.
CAUTION:
• Do not reuse side oil seal.
• Do not incline the new side oil seal when installing.
• Apply multi-purpose grease to the lips of the new side oil
seal.
2. Install the side flange using Tool.
a. Install the Tool to the side oil seal as shown.
b. Insert the side flange until the serrated part of the side flange
has engaged the serrated part of the side gear and remove the
Tool.
c. Drive in the side flange using suitable tool.
NOTE:
Installation is completed when the driving sound of the side
flange turns into a sound which seems to affect the whole rear
final drive assembly.
