c. Install the differential carrier assem-
bly into differential case in the re-
verse order of disassembling.
d. Fit the selected shims and O-ring on
side bearing retainer and install
them on differential case with the
arrow mark on the retainer directed
as shown in Figure.
NOTE:
Be careful that side bearing cup is not
damaged by bearing roller.

f. Measure the drive gear-to-drive pin-
ion backlash.
If the reading is not within the
specified range, correct by decreas-
ing 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.

g. At the same time, measure the
turning resistance of drive pinion.
Compared with the resistance when
differential carrier is not installed,
if the increase of the resistance is
not within the specified range,
readjust side bearing retainer shims.

h. Recheck drive gear-to-pinion back-
lash after readjusting shims.
i. Check the drive gear runout on its
back surface, and make sure pinion
and drive gear rotate smoothly.

15) Checking and adjusting tooth con-
tact of drive gear.
a. 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.
b. When the contact pattern is incor-
rect, readjust according to the in-
structions given in ''Tooth contact
pattern" .

Be sure to wipe off red lead com-
pletely upon completion of adjust-
ment.
c. After completing the above adjust-
ment, install oil seal in side bearing
retainer.
NOTE:
a. Use Drift (398437700) to press the
oil seal into position.
b. Apply chassis grease between the
oil seal lips.
d. Install rear cover.

7. Mounting
a. Raise differential assembly using a
jack. Remount the differential as-
sembly by temporarily tightening
four mounting nuts at the front and
two mounting nuts at the rear.
b. Install other parts in the reverse
order of dismounting.
c. After installation fill differential
case with gear oil to the upper plug
level.
