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.
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 toFFD-27, "
Differential Side
Gear Clearance".
6. Drive a lock pin into pinion mate shaft, using suitable tool.
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 recommended thread locking sealant into the thread hole
of drive gear. Refer toFFD-17, "
COMPONENTS".
CAUTION:
Make sure the drive gear back and threaded holes are
clean.

torque. Refer toFFD-17, "
COMPONENTS".
CAUTION:
lTighten bolts in a crisscross pattern.
lAfter tightening the bolts to the specified torque, tighten
the bolts additionally by turning the bolts 34 to 39
degrees.
10. Press side bearing inner races to differential case, using Tools.
CAUTION:
Do not reuse side bearing inner race.
11. Install housing spacer.
12. Apply gear oil to side bearings, and install differential case
assembly with side bearing outer races into gear carrier.
