Measure the rotating torque frequently to avoid excessively preloading the pinion bearings.
c. If the maximum tightening torque is reached prior to achieving the desired rotating torque, remove the pinion yoke and increase the thickness
of the solid shim pack. Increasing the shim pack thickness by 0.025 mm (0.001 inch) will decrease the rotating torque approximately 0.9 Nm
(8 inch lbs.).
Check Pinion Gear Rotation Torque
14. Check bearing rotating torque with an inch pound torque wrench. The torque necessary to rotate the pinion gear should be:
-
Original Bearings - 1 to 3 Nm (10 to 20 inch lbs.).
-
New Bearings - 2 to 5 Nm (15 to 35 inch lbs.).
15. Align previously made marks on yoke and propeller shaft and install propeller shaft.
16. Install differential housing into the axle housing.
FINAL ASSEMBLY
Typical Housing Cover With Sealant
1. Scrape the residual sealant from the housing and cover, mating surfaces. Clean the mating surfaces with mineral spirits. Apply a bead of MOPAR
Silicone Rubber Sealant, or equivalent, on the housing cover.
Install the housing cover within 5 minutes after applying the sealant.
2. Install the cover on the differential with the attaching bolts. Install the identification tag. Tighten the cover bolts to 41 Nm (30 ft. lbs.) torque.
CAUTION: Overfilling the differential can result in lubricant foaming and overheating.
