REASSEMBLY
1. CONVENTIONAL DIFFERENTIAL ONLY:
ADJUST DIFFERENTIAL PINION GEAR BACKLASH
(a) Install the proper thrust washers on the side gears.
HINT:
Using the table below, select thrust washers which will ensure
that the backlash is within the specification.
Thrust washer thickness
Thickness mm (in.)Thickness mm (in.)
1.6 (0.063)1.8 (0.071)
1.7 (0.067)-
(b) Install the side gears, pinion gears, pinion gear thrust
washers and pinion shaft in the differential case.
HINT:
Align the holes of the differential case and pinion shaft.
(c) Push the side gear shafts gently into the differential case
by hand and install them.
(d) Using a dial indicator, 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 different
thickness side gear thrust washers.
(e) Remove the side gear shaft.
2. CONVENTIONAL DIFFERENTIAL ONLY:

14. MEASURE TOTAL PRELOAD
Using SST (or a 36 mm deep socket) and a torque wrench,
measure the preload with the teeth of the drive pinion and ring
gear in contact.
SST 09229-55010
Total preload (at starting)
Drive pinion preload plus
2JZ-GTE M/T0.4 - 0.6 N´m (4 - 6 kgf´cm, 3.5 - 5.2 in.´lbf)
Others0.5 - 0.8 N´m (5 - 8 kgf´cm, 4.3 - 6.9 in.´lbf)
If the measured preload is less than the specification, replace
the washer of the ring gear's tooth surface side with a thicker
one.
If the preload is greater than the specification, replace the
washer of the ring gear's tooth surface side with thinner one.
HINT:
Changing the washer thickness by 0.02 mm (0.0008 in.) will
change the total preload by approx. 0.1 N´m (1 kgf´cm, 0.9
in.´lbf).
15. INSPECT TOOTH CONTACT PATTERN
(a) Coat 3 or 4 teeth at 3 different positions on the ring gear
with red lead primer.
(b) Hold the companion flange firmly and rotate the ring gear
in both directions.
(c) Inspect the tooth contact pattern.
