Differential / Front Axle - 186FIA
INSTALLATION

NOTE: If differential bearings or differential case are replaced, refer to Adjustments for Differential Bearing Preload and Gear Backlash procedures.

1. Position Spreader W-129-B on differential location holes and install safety hold down clamps. Tighten the tool turnbuckle finger-tight.
2. Install Pilot Stud C-3288-B to the left side of the differential housing. Attach Dial Indicator C-3339 to pilot stud. Load the indicator plunger against the opposite side of the housing and zero the indicator.
3. Spread the housing to install the differential case and preload shims in the housing. Measure the distance with the dial indicator.

CAUTION: Never spread the differential housing over 0.34 mm (0.013 in.). If housing is over-spread, it could be distorted or damaged.

4. Remove the dial indicator.
5. Install differential case in the housing. Ensure differential bearing cups remain on the bearings and preload shims are seated in the housing. Tap differential case to ensure bearings cups are seated in the housing.
6. Install bearing caps to their original locations and loosely install cap bolts.






7. Remove differential housing spreader (Fig. 43).
8. Tighten the bearing cap bolts in a cries-cross pattern to 54 - 68 Nm (39 - 50 ft. lbs.).
9. Install the right axle shaft.
10. Apply a 6.38 mm (1/4 in.) bead of red Mopar Silicone Sealer or equivalent to the housing cover.

CAUTION: If cover is not installed within 3 to 5 minutes, the cover must be cleaned and new RTV applied or adhesion quality will be compromised.

11. Install differential housing cover and tighten bolts in a cries-cross pattern to 19 - 26 Nm (14 - 19 ft. lbs.).
12. Install axle assembly in vehicle.
13. Fill differential with lubricant and install fill plug.
