DIFFERENTIALS
(5) Measure the hypoid driven gear-to-drive
pinion backlash. Set the magnet base on differ-
ential carrier. Align the contact point of dial
gauge with tooth face of hypoid driven gear, and
move hypoid driven gear while holding drive
pinion still. Read the value indicated on dial
gauge.
NOTE:
If measured value of backlash is not within the
specified range, repeat the procedures for pinion
driven gear set backlash adjustment and the differ-
ential side bearing preload adjustment.
Backlash:
0.10 — 0.15 mm (0.0039 — 0.0059 in)
17) Put alignment marks on both the differential
carrier and holder. Remove the holder side at a
time.
Replace them in the original position after inserting
an O-ring and applying grease to the threaded por-
tion.

18) Tighten the bolt of lock plate to specified
torque.
Tightening torque:
25 N·m (2.5 kgf-m, 18.4 ft-lb)
19) Recheck the hypoid driven gear to pinion back-
lash.
Backlash:
0.10 — 0.15 mm (0.0039 — 0.0059 in)

20) Checking and adjusting the tooth contact of hy-
poid driven gear
(1) Apply an even coat of red lead on both sides
(A)
of three or four teeth on the hypoid driven gear.
Check the contact pattern after rotating the hy-
poid driven gear several revolutions back and
forth until a definite contact pattern appears on
the hypoid driven gear.
(2) When the contact pattern is not correct, re-
adjust.
NOTE:

Be sure to wipe off the red lead completely after the
adjustment is completed.
