OPERATION
The differential assembly is driven by the transfer
shaft by way of the differential ring gear. The ring
gear drives the differential case, and the case drives
the driveshafts through the differential gears. The
differential pinion and side gears are supported in
the case by thrust washers and a pinion shaft. Dif-
ferential pinion and side gears make it possible for
front tires to rotate at different speeds while corner-
ing.
DISASSEMBLY
NOTE: The differential is serviced as an assembly.
The only parts that are serviceable within the differ-
ential are the differential bearing cups and cones. If
any other part fails within the differential, you must
replace the differential assembly along with the
transfer shaft.
The transfer shaft should be removed for differen-
tial repair and bearing turning torque checking. (1) Remove the differential cover and bolts (Fig.
169) (Fig. 170).
(2) Remove the differential bearing retainer and
bolts (Fig. 171) (Fig. 172). (3) Using a plastic hammer, remove extension
housing/adapter plate on the right side of the trans-
axle.
WARNING: HOLD ONTO DIFFERENTIAL ASSEMBLY
TO PREVENT IT FROM ROLLING OUT OF HOUSING.
(4) Remove differential assembly.

MEASUREMENT AND ADJUSTMENT
NOTE: Perform all differential bearing preload mea-
surements with the transfer shaft and gear
removed. DIFFERENTIAL BEARING PRELOAD ADJUSTMENT USING
EXISTING SHIM
(1) Position the transaxle assembly vertically on
the support stand, differential bearing retainer side
up. (2) Install Tool L-4436A into the differential and
onto the pinion mate shaft (Fig. 185).
(3) Rotate the differential at least one full revolu-
tion to ensure the tapered roller bearings are fully
seated. (4) Using Tool L-4436A and an inch-pound torque
wrench, check the turning torque of the differential
(Fig. 186). The turning torque should be
between 5 and 18 inch-pounds.

(5) If the turning torque is within specifications,
remove tools. Setup is complete. (6) If turning torque is not within specifications
proceed with the following steps. (a) Remove differential bearing retainer from
the transaxle case. (b) Remove the bearing cup from the differential
bearing retainer using Tool 6062A. (c) Remove the existing shim from under the
cup. (d) Measure the existing shim.
(e) If the turning torque was too high when mea-
sured, install a 0.05 mm (0.002 inch) thinner shim.
If the turning torque is was too low, install a 0.05
mm (0.002 inch) thicker shim. Repeat until 5 to 18
inch-pounds turning torque is obtained. Oil Baffle
is not required to be installed when making shim
selection. (f) Install the proper shim under the bearing
cup. Make sure the oil baffle is installed properly in the bearing retainer, below the bearing shim
and cup.
(g) Install the differential bearing retainer using
Tool 5052 and C-4171. Seal the retainer to the
housing with MOPAR tAdhesive Sealant and
torque bolts to 28 N´m (250 in. lbs.).
(7) Using Tool L-4436A and an inch-pound torque
wrench, recheck the turning torque of the differential
(Fig. 186). The turning torque should be
between 5 and 18 inch-pounds. Shim thickness need be determined only if any of
the following parts are replaced: ² Transaxle case
² Differential carrier
² Differential bearing retainer
² Extension housing
² Differential bearing cups and cones

PRELOAD ADJUSTMENT W/O SHIM(1) Remove the bearing cup from the differential
bearing retainer using Miller special Tool 6062A. (2) Remove existing shim from under bearing cup.
(3) Reinstall the bearing cup into the retainer
using Miller Special Tool 6061, and C-4171.
NOTE: Oil baffle is not required when making the
shim calculation.
(4) Install the bearing retainer into the case.
Torque bolts to 28 N ²m (250 in. lbs.).
(5) Position the transaxle assembly vertically on
the support stand and install Miller Special Tool
L-4436-A into the bearing retainer. (6) Rotate the differential at least one full revolu-
tion to ensure the tapered roller bearings are fully
seated. (7) Attach a dial indicator to the case and zero the
dial. Place the tip on the end of Special Tool
L-4436-A. (8) Place a large screwdriver to each side of the
ring gear and lift. Check the dial indicator for the
amount of end play.
CAUTION: Do not damage the transaxle case and/or
differential retainer sealing surface.
(9) Using the end play measurement that was
determined, add 0.18mm (0.007 inch). This should
give you between 5 and 18 inch pounds of bearing
preload. Refer to the Differential Bearing Shim Chart
to determine which shim to use. (10) Remove the differential bearing retainer.
Remove the bearing cup. (11) Install the oil baffle. Install the proper shim
combination under the bearing cup. (12) Install the differential bearing retainer. Seal
the retainer to the housing with Mopar tSilicone
Rubber Adhesive Sealant. Torque bolts to 28 N ²m
(250 in. lbs.). (13) Using Miller Special Tool L-4436-A and an
inch-pound torque wrench, check the turning torque
of the differential (Fig. 186). The turning torque
should be between 5-18 inch-pounds.
NOTE: If turning torque is too high install a 0.05mm
(0.002 inch) thicker shim. If the turning torque is too
low, install a 0.05mm (0.002 inch) thinner shim.
Repeat until 5-18 inch-pounds of turning torque is
obtained.FLUID
STANDARD PROCEDURE
FLUID LEVEL AND CONDITION CHECK
NOTE: Only transmission fluid of the type labeled
Mopar ATF+4 (Automatic Transmission Fluid)
should be used in this transaxle.
FLUID LEVEL CHECK
The transmission sump has a fluid level indicator
(dipstick) to check oil similar to most automatic
transmissions. It is located on the left side of the
engine. Be sure to wipe all dirt from dipstick handle
before removing. The torque converter fills in both the P Park and N
Neutral positions. Place the selector lever in P Park
to be sure that the fluid level check is accurate. The
engine should be running at idle speed for at
least one minute, with the vehicle on level
ground. At normal operating temperature 82É C
(180É F), the fluid level is correct if it is in the HOT
region on the oil level indicator (Fig. 187). The fluid
level should be within the COLD region of the dip-
stick at 27É C (80É F) fluid temperature.
FLUID LEVEL CHECK USING DRB
NOTE: Engine and Transaxle should be at normal
operating temperature before performing this proce-
dure.
(1) Start engine and apply parking brake.
(2) Hook up DRB scan tool and select transmis-
sion.
