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. 401).

3 – DIFFERENTIAL BEARING RETAINER
(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. 402). The turning
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.05 mm (.002 inch) thinner shim. If
the turning torque is was too low, install a.05 mm
(.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 selec-
tion.
(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
torque bolts to 28 N·m (250 in. lbs.).

• Differential carrier
• Differential bearing retainer
• Extension housing
