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.

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.
± SUSPENSION AND AXLEREAR DIFFERENTIALSA±65

1. 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
(c) Using a screwdriver, remove the snap ring from the side gear
shaft.
2. REMOVE SIDE GEAR SHAFT OIL SEALS
Using SST, remove the oil seal.

3. REMOVE DIFFERENTIAL CARRIER RETAINER (AND
ADJUSTING PLATE WASHER)
(a) Remove the 8 bolts.
(b) 2JZ±GTE M/T:
Using SST, remove the carrier retainer and adjusting plate
washer.
SST 09550±10012 (09558±10010),
09950±40010
Except 2JZ±GTE M/T:
Using 2 screwdrivers, remove the carrier retainer.
(c) Using a screwdriver, remove the O±ring from the carrier
retainer. SA±66
