 At first, using a hammer, tap bearing outer race until it
becomes flat to gear carrier.
 Never reuse pinion front and rear bearing outer race.
2. Select drive pinion height adjusting washer. Refer to "Pinion Gear Height".
3. Install selected drive pinion height adjusting washer (2) to drive pinion. Press pinion rear bearing inner race (1) to it, using drift.
CAUTION:
 Pay attention to the direction of pinion height adjustingwasher. (Assemble as shown in the figure.)
 Never reuse pinion rear bearing inner race.
4. Assemble collapsible spacer to drive pinion. CAUTION:
Never reuse collapsible spacer.
5. Apply gear oil to pinion rear bearing, and assemble drive pinion into gear carrier.
6. Apply gear oil to pinion front bearing, and assemble pinion front bearing inner race to drive pinion assembly.
CAUTION:
Never reuse pinion front bearing inner race.
7. Using suitable spacer (A), press the pinion front bearing inner race to drive pinion as far as drive pinion nut can be tightened.Tool number A: ST30720000 (J-25405)

8. Using the drift, install front oil seal as shown in figure.
CAUTION:
 Never reuse oil seal.
 When installing, never incline oil seal.

10. Apply anti-corrosion oil to the thread and seat of drive pinion lock nut, and temporarily tighten drive pinion lock nut to drive pinion.
CAUTION:
Never reuse drive pinion lock nut.
11. Adjust to the drive pinion lock nut tightening torque and pinion bearing preload torque.
CAUTION:
 Adjust to the lower limit of the drive pinion lock nut tight-
ening torque first.
 If the preload torque exceeds the specified value, replace collapsible spacer and tighte n it again to adjust. Never
loosen drive pinion lock nut to adjust the preload torque.
 After adjustment, rotate dri ve pinion back and forth 2 to 3
times to check for unusual no ise, rotation malfunction,
and other malfunctions.
12. Install differential case assembly. Refer to "Differential Assem- bly".
CAUTION:
Never install rear cover yet.
13. Check and adjust drive gear runout, tooth contact, drive gear to drive pinion backlash, and companion
flange runout. Refer to "Drive Gear Runout", "Tooth Contact", "Backlash", "Companion Flange Runout".
Recheck above items. Readjust the above description, if necessary.
14. Check total preload torque. Refer to "Total Preload Torque".
15. Install rear cover. Refer to "Differential Assembly". Tool number A: ST30720000 (J-25405)

Differential Assembly
1. Install side gear thrust washers with the same thickness as theones installed prior to disassembly or reinstall the old ones on
the side gears.
2. Install side gears and thrust washers into differential case. CAUTION:
Make sure that the circular clip is installed to side gears.
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 to "Differential Side Gear Clear-
ance".
6. Drive a lock pin into pinion mate shaft, using a punch. Make sure lock pin is flush with differential case.
CAUTION:
Never reuse lock pin.
