INSTALLATION

NOTE: If replacement differential side bearings or differential case are being installed, it is necessary to measure and adjust Differential Side Bearing Preload and Gear Backlash. Refer to Adjustments - Differential Side Bearing Preload and Gear Backlash to determine proper snap ring selection.





1. Install differential assembly (1) into axle housing. Note: If difficulty installing differential is encountered due to interference with spreader and plates, remove axle housing from spreader, plates from housing, and install differential. Return assembly to the spreader.





2. Install differential side bearing cups (2). Use tool 9522 (1) to aid in differential alignment.





3. Use Tool 9522 (1) to aid in seating side bearing cups (2).





4. Set up Dial Indicator Set C-3339-A to measure housing spread as shown:
a. Clamp SP-5426 (1)
b. Post SP-5425-B (2)
c. Metric Dial Indicator 9524 (3)





5. Expand spreader W-129-B (1) to spread axle housing no more than 0.30 mm (0.012 inch).

NOTE: The differential side bearing snap rings are select-fit, and control ring gear backlash and differential side bearing preload. It is necessary to return snap rings to their original position. If replacement differential side bearings, differential case, or axle housing are being installed, refer to Adjustments - Differential Side Bearing Preload and Gear Backlash to determine proper snap ring selection.





6. Using suitable snap ring pliers (2), install differential side bearing snap rings (1).





7. Back off W-129-B spreader (1) to relax tension on housing.





8. Remove axle assembly from spreader. Remove plates (1).





9. Apply 4 mm (0.157 inch) bead (2) of Mopar Axle RTV to axle housing cover (1) as shown.





10. Install cover (2) to axle housing. Install and torque cover-to-housing bolts (1) to 30 Nm (22 ft. lbs.) + 90°.





11. Install axle seals (1) using Tool 9223 (2).
