13. Remove the J34309 pinion preload shim selector tool from the
final drive housing and disassemble to retrieve the pinion bear-

TOOTH CONTACTNBPD0040S02Gear tooth contact pattern check is necessary to verify correct
relationship between ring gear and drive pinion.
Hypoid gear sets which are not positioned properly in relation to
one another may be noisy, or have short life or both. With a pat-
tern check, the most desirable contact for low noise level and long
life can be assured.

1. Thoroughly clean ring gear and drive pinion teeth.
2. Sparingly apply a mixture of powdered ferric oxide and oil or
equivalent to 3 or 4 teeth of ring gear drive side.

3. Hold companion flange steady by hand and rotate the ring gear
in both directions.

9. Turn drive pinion in both directions several times, and measure
pinion bearing preload.
Tool number: ST3127S000 (J25765-A)
Pinion bearing preload (Without front oil seal):
1.2 - 2.0 N´m (12 - 20 kg-cm, 10 - 17 in-lb)
If preload is out of specification, adjust the thickness of spacer and
shim combination by replacing shim and spacer with thinner one.
IStart from the combination of thickest spacer and shim.
ICombine each spacer and shim thickness one by one until the
correct specification are achieved.
Drive pinion bearing preload adjusting spacer and
shim:
Refer to SDS, PD-64.
10. Install differential case assembly with side bearing outer races
into gear carrier.
11. Position side bearing adjusters on gear carrier with threads
properly engaged; screw in adjusters lightly at this stage of
assembly.
Tool number: ST32580000 (J34312)

12. Align mark on bearing cap with that on gear carrier and install
bearing cap on gear carrier.
IDo not tighten at this point to allow further tightening of side
bearing adjusters.

13. Tighten both right and left side bearing adjusters alternately
and measure ring gear backlash and total preload at the same
time. Adjust right and left side bearing adjusters by tightening
them alternately so that proper ring gear backlash and total
preload can be obtained.
Ring gear-to-drive pinion backlash:
0.13 - 0.18 mm (0.0051 - 0.0071 in)

tions several times to set bearing rollers.

tion.

16. Check runout of ring gear with a dial indicator.
Runout limit: 0.08 mm (0.0031 in)
IIf backlash varies excessively in different places, the variance
may have resulted from foreign matter caught between the ring
gear and the differential case.
IIf the backlash varies greatly when the runout of the ring gear
is within a specified range, the hypoid gear set or differential
case should be replaced.
17. Check tooth contact. Refer to ªTOOTH CONTACTº, PD-56.
