AWD SYSTEM
[W2F1] 3-4
The correct shims are as follows
Thickness Q'ty
0.25 x 1 = 0.25
0 .30 x 1 = 0.30
Total shim thickness = 0.55 mm
Right side
TZ = (B + D + GZ) x 0.01 + 0 .76 - F
= (3+ 3+ 3)x0 .01 + 0.76-0.10
= 0 .09 + 0 .76-0.10
= 0 .75 mm
The correct shims are as follows
Thickness Q'ty
0 .25 x 1 = 0.25
0 .50
x 1 = 0.50
Total shim thickness = 0.75 mm
(3) Install the differential case ASSY into differential
carrier in the reverse order of disassembling.
(4) Fit the selected shims and O-ring on side bearing
retainer and install them on differential carrier with
the arrow mark on the retainer directed as shown in
Figure .
Be careful that side bearing cup is not damaged by
bearing roller .

(5) Tighten side bearing retainer bolts .
On vehicle with LSD, apply a coat of Three Bond 1215
(P/N 004403007) to threads.
Torque (Side bearing retainer) :
9 - 12 N"m (0.9 - 1 .2 kg-m, 6.5 - 8.7 ft-Ib)
(6) Measure the drive gear-to-drive pinion backlash .
If the reading is not within the specified range, correct
by decreasing the shim thickness on one side and
increasing the shim thickness on the other side the
same amount . Total shim thickness must be the same
to maintain proper preload.
Backlash : 0 .10 - 0.20 mm (0 .0039 - 0.0079 in)

(7) At the same time, measure the turning resistance
of drive pinion . Compared with the resistance when
differential case is not installed, if the increase of the
resistance is not within the specified range, readjust
side bearing retainer shims.
Turning resistance increase:
0.1 - 0.6 N"m (1 - 6 kg-cm, 0.9 - 5.2 in-Ib)
(8) Recheck drive gear-to-pinion backlash after read-
justing shims.
(9) Check the drive gear runout on its back surface,
and make sure pinion and drive gear rotate smoothly .
Limit of runout :
0.05 mm (0.0020 in)

15) Checking and adjusting tooth contact of drive gear .
(1) Paint evenly both sides of three or four teeth on
drive gear with red lead . Check the contact pattern
after rotating drive gear several revolutions back and
forth until definite contact pattern develops on drive
gear .
(2) When the contact pattern is incorrect, readjust
according to the instructions given in "Tooth contact
pattern" .
