DISASSEMBLY
NOTE: The differential is serviced as an assembly.
Service is limited to bearing cups and cones. Any
other failure must be repaired by differential assem-
bly and transfer shaft replacement.
(1) Remove transfer shaft.
(2) Measure differential bearing turning torque.
(Refer to 21 - TRANSMISSION/TRANSAXLE/AUTO-
MATIC - 31TH/BEARINGS - ADJUSTMENTS)
(3) Remove adapter plate seal.
(4) Remove differential cover-to-transaxle case
bolts (Fig. 140).
(5) Remove differential cover (Fig. 141). Clean sur-
faces of old adhesive prior to reassembly.
(6) Remove bearing retainer axle seal using slide
hammer C-637 and Tool 7794A, or Tool L-4518.
(7) Remove differential bearing retainer-to-trans-
axle case bolts (Fig. 142).

(8) Remove bearing retainer from transaxle. Use to
L-4435 to aid in removal by rotating retainer out of
assembly (Fig. 143). Clean surfaces of old adhesive
prior to reassembly.
(9) Remove adapter plate-to-transaxle case bolts.WARNING: HOLD ON TO DIFFERENTIAL WHILE
REMOVING EXTENSION HOUSING TO PREVENT IT
FROM ROLLING OUT OF TRANSAXLE.

(10) Remove extension housing from transaxle
case. Use Tool L-4435 to aid in removal by rotating
plate out of assembly. Clean surfaces of old adhesive
prior to reassembly.
(11) Measure and record differential side gear end
play using dial indicator C-3339 and Tool C-4995 as
shown in (Fig. 144) and (Fig. 145).Side gear end
play must be within 0.001-0.013 in. Replace dif-
ferential assembly if outside this range.(12) Remove differential bearing cone (from exten-
sion housing side) using Tool C-293, and adapters
C-293-3, and C-293-36 (Fig. 146).
(13) Set up tools as shown in (Fig. 147) and (Fig.
148) to facilitate differential bearing removal from
ring gear side.

ASSEMBLY
NOTE: The differential is serviced as an assembly.
Service is limited to bearing cups and cones. Any
other failure must be repaired by differential assem-
bly and transfer shaft replacement.
(1) Install shim and bearing cup using Tool 5052
and driver handle C-4171 (Fig. 152). Install bearing
cup into extension housing using Tool 6536 and
driver handle C-4171.
(2) Position bearing cone onto differential (Fig.
153), and install bearing cone using Tool 6536 and
driver handle C-4171 (Fig. 154).(3) Measure side gear end play using dial indicator
C-3339 and Tool C-4996 (Fig. 155) (Fig. 156).Side
gear end play must be between 0.001 and 0.013
in.
(4) Apply a bead of Moparž Silicone Rubber Adhe-
sive Sealant to the adapter plate. Load differential
assembly into position and install adapter plate .
(5) Using Tool L-4435, index adapter plate until
bolt holes align.
(6) Install adapter plate-to-transaxle case bolts
and torque to 28 N´m (250 in. lbs.) torque.
