9. Turn drive pinion in both directions several revolutions, and
measure pinion bearing preload.
Tool number: ST3127S000 (J25765-A)
Pinion bearing preload:
1.1 - 1.4 N´m (11 - 14 kg-cm, 9.5 - 12.2 in-lb)
When pinion bearing preload is outside the specifications,
replace pinion bearing adjusting washer and spacer with a
different thickness.

16. Measure ring gear to drive pinion backlash with a dial indica-
tor.
Ring gear-to-drive pinion backlash:
0.10 - 0.15 mm (0.0039 - 0.0059 in)
IIf backlash is too small, decrease thickness of right shim and
increase thickness of left shim by the same amount.
If backlash is too great, reverse the above procedure.
Never change the total amount of shims as it will change the
bearing preload.
SPD664
17. Check total preload with Tool.
When checking preload, turn drive pinion in both direc-
tions several times to set bearing rollers.
Tool number: ST3127S000 (J25765-A)
Total preload:
P
1+ [0.3 - 1.5 N´m (3 - 15 kg-cm, 2.6 - 13.0 in-lb)]
P
1: Drive pinion preload
SPD561
IIf preload is too great, remove the same amount of shim from
each side.
IIf preload is too small, add the same amount of shim to each
side.
Never add or remove a different number of shims for each side
as it will change ring gear to drive pinion backlash.
18. Recheck ring gear to drive pinion backlash because increase
or decrease in thickness of shims will cause change of ring
gear-to-pinion backlash.
SPD524
19. Check runout of ring gear with a dial indicator.
Runout limit:
0.05 mm (0.0020 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.
20. Check tooth contact. Refer to ªTOOTH CONTACTº, PD-29.
21. Install rear cover and gasket.
