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.)

washers and pinion shaft in the differential case.

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.
