INSTALLATION

NOTE: If replacement differential bearings or differential case are being installed, differential side bearing shim requirements may change. Refer to Adjustments (Differential Bearing Preload and Gear Backlash) procedures to determine proper shim selection.

1. Position Spreader W-129-B with the tool dowel pins seated in the locating holes. Install the hold down clamps and tighten the tool turnbuckle finger tight.
2. Install a Pilot Stud C-3288-B at the left side of the differential housing and attach dial indicator to the pilot stud. Load the indicator plunger against the opposite side of the housing and zero the dial indicator.
3. Spread the housing enough to install the case in the housing. Measure the distance with the dial indicator.

CAUTION: Do not spread over 0.50 mm (0.020 in). If the housing is over-spread, it could be distorted or damaged.

4. Remove the dial indicator.





5. Install differential into the housing. Tap the differential case with a rawhide/rubber hammer to ensure the bearings are seated in housing (Fig. 32).
6. Remove the spreader.





7. Install bearing caps in their original locations (Fig. 33) and tighten bearing cap bolts to 109 Nm (80 ft. lbs.).
8. Install axle shafts.
9. Install the hub bearings.





10. Apply a bead of Mopar Silicone Rubber Sealant or equivalent to the housing cover (Fig. 34).
Install the housing cover within 5 minutes after applying the sealant.
11. Install the cover and any identification tag. Tighten the cover bolts in a criss-cross pattern to 47 Nm (35 ft. lbs.).
12. Refill the differential with Mopar Hypoid Gear Lubricant or equivalent to bottom of the fill plug hole. Refer to the Lubricant Specifications for correct quantity and type.
13. Install the fill hole plug and tighten to 34 Nm (25 ft. lbs.).
14. Remove support and lower vehicle.
