PINION/G. PINION SHAFT(1) First assemble the spacer on the rear of the side gear
&aand then assemble the gear in the differential case.
.--(2) Assemble the washer on the rear of the pinion, and
position in the designated place by rotating the two sidegears at the same time so they mesh.
(3) Insert the pinion shaft.
(4) Measure the backlash between the side gear and
pinion.Standard value:
0.025-0.150 mm (.OOl-.0059 in.)(5) If backlash is outside the standard value, select a
spacer, disassemble the gear again, reassemble and
adjust.
NOTELd
Adjust so backlash in both side gears is the same.

5. INSTALLATION OF LOCK PINAlign the lock pin hole in the pinion shaft and the lock pin
hole in the case and then install the lock pins.Caution
1. Do not reuse lock pins (F4A22wW4A33).
2. Make the lock pin lower than the surface of thedifferential
case flange.
3. Press-fitting load is over 5,000 N (1,100 Ibs.)
(F4A22sW4A33).
4. INSTALLATION OF TAPER ROLLER BEARINGUsing the special tool, press-fit the taper roller bearing in
the differential case.
3. INSTALLATION OF BALL BEARINGUsing the special tool, press-fit the ball bearing in the
differential case.
1. INSTALLATION OF BOLTSApply ATF to the differential drive gear bolts, install and
tighten with specified torque in the order shown in the
figure.Differential drive gear bolt:
