adjustments must be made with no other component
interference or gear intermesh.
(4) Replace bearings as a pair: If one differential
bearing is defective, replace both differential bear-
ings, if one input shaft bearing is defective, replace
both input shaft bearings.
(5) Bearing cones must not be reused if removed.
(6) Turning–torque readings should be obtained
while smoothly rotating in either direction.
DIFFERENTIAL BEARING PRELOAD ADJUSTMENT
NOTE: True bearing turning–torque readings can
be obtained only with the geartrain removed from
the case.
(1) Remove bearing cup and existing shim from
clutch bellhousing case.
(2) Press in new bearing cup into bellhousing case
(or use a cup that has been ground down on the
outer edge for ease of measurement).
(3) Press in new bearing cup into gear case side.

(4) Oil differential bearings with Mopar type M.S.
9417 Manual Transaxle Fluid. Install differential
assembly in transaxle gear case. Install clutch bell-
housing over gear case. Install and torque case bolts
to 29 N·m (21 ft. lbs.).
(5) Position transaxle with bellhousing facing
down on workbench with C-clamps. Position dial
indicator.
(6) Apply a medium load to differential with Tool
C-4995 and a T-handle, in the downward direction.
Roll differential assembly back and forth a number of
times. This will settle the bearings. Zero the dial
indicator. To obtain end play readings, apply a
medium load in an upward direction while rolling
differential assembly back and forth (Fig. 76). Record
end play.
Fig. 76 Checking Differential Bearing End Play To
Determine Shim Thickness
(7) The shim required for proper bearing preload is
the total of end play, plus (constant) preload of
0.18mm (0.007 in.). Never combine shims to obtain
the required preload.
(8) Remove case bolts. Remove clutch bellhousing
differential bearing cup. Install shim(s) selected in
Step 7. Then press the bearing cup into clutch bell-
housing.
(9) Install clutch bellhousing. Install and torque
case bolts to 26 N·m (19 ft. lbs.).
(10) Using Special Tool C-4995 and an inch-pound
torque wrench, check turning torque of the differen-
tial assembly (Fig. 77). The turning torque should
be 6 to 12 in. lbs. If the turning torque is too
high, install a 0.05mm (0.002 inch) thinner shim.
If the turning torque is too low, install a
0.05mm (0.002 inch) thicker shim.
(11) Recheck turning torque. Repeat Step 10 until
the proper turning torque is obtained.
Once proper turning torque has been established,
place gear case on the end plate. Draw a bead of
