SIDE GEAR SHAFT OIL SEAL
REPLACEMENT
1. DRAIN DIFFERENTIAL OIL
2. REMOVE REAR DRIVE SHAFT
(See page SA±46)
3. REMOVE SIDE GEAR SHAFT
(a) 2JZ±GTE M/T only:
Equally tighten both bolts at the same time and pull out the
side gear shaft.
NOTICE: Pull out the side gear shaft until a nut can fit be-
hind the shaft. Pulling the shaft out too far will damage
the dust cover.
(b) Using SST and 2 bolts, nuts, remove the side gear shaft.
SST 09520±24010
4. REMOVE SNAP RING
Remove the snap ring from the side gear shaft.
5. REMOVE SIDE GEAR SHAFT OIL SEAL
Using SST, remove the oil seal.
SST 09308±00010
6. INSTALL SIDE GEAR SHAFT OIL SEAL
(a) Using SST and a hammer, drive in a new oil seal.
2JZ±GTE M/T:
SST 09223±15030, 09608±35014 (09608±06020)
Except 2JZ±GTE M/T:
SST 09608±32010, 09608±35014 (09608±06020)
(b) Apply MP grease to the oil seal lip. SA±58
± SUSPENSION AND AXLEREAR DIFFERENTIAL

7. INSTALL SIDE GEAR SHAFT
(a) Install a new snap ring to the side gear shaft.
(b) Coat MP grease onto the snap ring.
(c) Using a hammer and brass bar, tap in the side gear shaft to
the differential.
NOTICE: Be careful not damage the side gear shaft and
oil seal.
HINT: Whether or not the side gear shaft is making contact
with the pinion shaft can be determined by the sound or feel-
ing when driving it in.
8. CHECK INSTALLATION OF SIDE GEAR SHAFT
Check that the side gear shaft will not come out by trying to
pull it out by hand.
9. INSTALL REAR DRIVE SHAFT
(See page SA±46)
10. FILL DIFFERENTIAL WITH OIL
Oil grade:
API GL±5 Hypoid gear oil
Viscosity:
Above ± 18°C (0°F) SAE 90
Below ± 18°C (0°F) SAE 80W±90 or 80W
Capacity:

DIFFERENTIAL REMOVAL
Installation is in the reverse order of removal.
1. DRAIN DIFFERENTIAL OIL
2. REMOVE PROPELLER SHAFT
(See page PR±5)
3. DISCONNECT BOTH REAR DRIVE SHAFTS FROM
DIFFERENTIAL
(a) Place matchmarks on the drive shaft and side gear shaft.
(b) Using a 10 mm hexagon wrench, disconnect both drive
shafts from the differential.
Torque: 83 NVm (850 kgfVcm, 64 ftVlbf)
INSTALLATION HINT: Apply a light coat of engine oil on the
threads of the bolts.
(c) Support both drive shafts securely.
4. REMOVE REAR STABILIZER BAR
(See page SA±96)
5. REMOVE DIFFERENTIAL
(a) Support the differential with a jack.
(b) Using a 12 mm hexagon wrench, remove the bolts.
Torque: 142 NVm (1,450 kgfVcm, 105 ftVlbf)
(c) Remove the 2 bolts and lower mount stoppers.
Torque: 147 NVm (1,500 kgfVcm, 108 ftVlbf)
(d) Remove the differential.
(e) Remove the upper mount stopper from the differential carrier.
HINT: During production, some vehicles did not need adjust-
ing shims to be fitted.
INSTALLATION HINT: Use the upper mount stopper which
was removed.

DIFFERENTIAL CARRIER INSPECTION
1. CHECK DRIVE PINION SHAFT RUNOUT
Measure the drive pinion shaft runout at a position 10 mm
(0.39 in.) from the end of the shaft.
Maximum runout:
0.08 mm (0.0031 in.)
If the runout is greater than the maximum, replace the drive
pinion and/or ring gear.
2. REMOVE DIFFERENTIAL CARRIER COVER
(a) Remove the 8 bolts from the carrier cover.
(b) Using a brass bar and hammer, separate the cover and
carrier.
3. CHECK RING GEAR RUNOUT
Maximum runout:
2JZ±GTE M/T
0.08 mm (0.0031 in.)
Except 2JZ±GTE M/T
0.05 mm (0.0020 in.)
If the runout is greater than the maximum, replace the drive
pinion, ring gear and/or differential case.
4. CHECK RING GEAR BACKLASH
Measure the backlash of the ring gear and drive pinion at 3
points (minimum) and check that the average value is within
the specification.
Backlash (average value):
0.08±0.13 mm (0.0031±0.0051 in.)
NOTICE: The difference between the maximum and minimum
measured values must be less than 0.05 mm (0.0020 in.).
If the backlash is not within the specification, adjust the ring
gear backlash.

5. MEASURE DRIVE PINION PRELOAD
Using SST (or a 36 mm deep socket) and a torque wrench,
measure the drive pinion preload using the backlash of the
drive pinion and ring gear.
SST 09229±55010
Preload (at start):
2JZ±GTE M/T
1.0±1.2 NVm (10±12 kgfVcm, 8.9±10.6 in.Vlbf)
Except 2JZ±GTE M/T
0.5±0.8 NVm (5±8 kgfVcm, 4.3±6.9 in.Vlbf)
6. CHECK TOTAL PRELOAD
Using SST (or a 36 mm deep socket) and a torque wrench,
measure the total preload.
SST 09229±55010
Total preload (at start):
In addition to drive pinion preload
2JZ±GTE M/T
0.4±0.6 NVm (4±6 kgfVcm, 3.4±5.2 in.Vlbf)
Except 2JZ±GTE M/T
0.5±0.8 NVm (5±8 kgfVcm, 4.3±6.9 in.Vlbf)
If necessary, disassemble and inspect the differential
7. CONVENTIONAL TYPE ONLY:
CHECK PINION GEAR BACKLASH
Measure the pinion gear backlash while holding one side
gear toward the case.
Backlash:
0.05±0.20 mm (0.0020±0.0079 in.)
If the backlash is not within the specification, install the cor-
rect thrust washer.
(See page SA±70)
8. CHECK TOOTH CONTACT PATTERN
(See page SA±75)
DIFFERENTIAL CARRIER DISASSEMBLY
HINT: When fastening the differential carrier to an overhaul
stand, etc., fasten it at the 4 places on the ring gear side
shown in the illustration.
