NOTE
When selecting the drive pinion front shims, if the number
of shims is large, reduce the number of shims to a minimum
by selecting the drive pinion spacers.

Adjust the differential gear backlash by the follow ing proce-
dures:
(1) Assemble the side gears, side gear spacers, pin ion gears,
and pinion washers into the differential case.
(2) Temporarily install the pinion shaft.
NOTE,
Do not drive in the lock pin yet.,
(3) While locking the side gear with the wedge,. me asure

(1) The measurement should be made for both pinion
gears individually.
(2) Refer to for measurement of slip

(4) If the differential gear backlash exceeds the l imit, adjust
the backlash by installing thicker side gear spacer s.
(5) Measure the differential gear backlash once aga in, and
confirm that it is within the limit.
NOTE
1. After adjustment, check that is less than
the limit and differential “gear rotates smoothly.
2. When adjustment is impossible,’ replace the side gear
and the pinion gear as a set.

LOCK PIN INSTALLATION
(1) Align the pinion shaft lock pin hole with the ‘ differential
case lock pin hole, and drive in the
pin.
(2) Stake the lock pin with a punch at, two points.
DRIVE GEAR INSTALLATION
(1) Clean the drive gear attaching bolts.
(2) Remove the adhesive adhering to the threaded ho les
of the drive gear by turning

Attach the differential pinion mate to the pinion s haft with
the pinion washers directed as shown, then assemble them

THRUST WASHER (L.H.) SELECTION
When the differential side gear and pinion mate gea r have
been replaced, select the thrust washer (L.H.) by the following
procedure.
(1) Wash the differential side gear and pinion mate gear
with unleaded gasoline and degrease.
(2) Assemble the thrust washers so far used, withou t
confusing the R.H. part with the L.H. part and toge ther
with each gear, VCU, pinion mate washer and pinion
shaft, to the differential cases (A) and (B), and l oosely
tighten the screws.
(3)Check the differential backlash, and select a thrus t washer
(L.H.) to obtain its standard value. (Refer to
