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.
I
Start from the combination of thickest spacer and shim.
I
Combine 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)
SPD265
12. Align mark on bearing cap with that on gear carrier and install
bearing cap on gear carrier.
I
Do not tighten at this point to allow further tightening of side
bearing adjusters.
SPD246
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)

I
When checking preload, turn drive pinion in both direc-
tions several times to set bearing rollers.

14. Tighten side bearing cap bolts.
15. Install side lock finger in place to prevent rotation during opera-
tion.
SPD247
16. Check runout of ring gear with a dial indicator.
Runout limit: 0.08 mm (0.0031 in)
I
If backlash varies excessively in different places, the variance
may have resulted from foreign matter caught between the ring
gear and the differential case.
I
If 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 “TOOTH CONTACT”, PD-56.
