ADJUSTMENT - DIFFERENTIAL BEARINGNOTE: Transfer shaft MUST be removed from transaxle to obtain an accurate differential turning torque measurement.
Differential turning torque should be measured and adjusted during any transaxle or differential teardown/assembly, or if any of the following parts are replaced:
- Transaxle case
- Differential carrier
- Differential bearing retainer
- Extension housing
- Differential bearing cups and cones
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. 163).
3. Rotate the differential at least one full revolution 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. 164). Turning torque should be within 5 - 18 inch lbs..
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 to obtain proper shim selection:
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.
NOTE: If the turning torque was too high when measured, 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 lbs. turning torque is obtained. Refer to the "Differential Bearing Shim Chart." On Baffle is not required when making shim selection.
e. 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.
f. Install the differential bearing cup, shim, and oil baffle using Tool 5052 and C-4171. Seal the retainer to the housing with MOPAR Silicone Rubber Adhesive Sealant and torque bolts to 28 Nm (250 inch lbs.).

7. Using Tool L-4436A and an inch-pound torque wrench, recheck differential tuning torque. Turning torque should be within 5 - 18 inch lbs.
