Ring and Pinion

REMOVAL

NOTE: The ring and pinion gears are serviced in a matched set. Never replace one gear without replacing the other gear.

1. Remove differential from housing.
2. Place differential case in a vise with soft metal jaw.
3. Remove ring gear bolts from the differential case.





4. Drive ring gear off the differential case with a dead-blow hammer (Fig. 64).
5. Unlock collared nut.
6. Hold pinion flange with Flange Wrench C-3281 and remove nut.





7. Remove pinion flange from pinion shaft with Puller 8892 and Wrench C-3281 (Fig. 65).
8. Remove pinion gear from housing with a deadblow hammer.
9. Remove pinion shaft seal with a seal pick.
10. Remove front pinion bearing.
11. Remove front pinion bearing cup with Remover D-103 and Handle C-4171.
12. Remove rear pinion bearing cup with Remover 9084 and Handle C-4171.
13. Remove pinion depth shim from rear pinion bearing cup bore.





14. Remove collapsible spacer (Fig. 66).





15. Remove spacer from pinion shaft (Fig. 67).





16. Remove rear bearing from pinion shaft with Puller/Press C-293-PA and Adapters C-293-47 (Fig. 68).

INSTALLATION

1. Apply Mopar Door Ease or equivalent lubricant to outside surface of bearing cups.
2. Install pinion depth shim in rear pinion bearing cup bore.
3. Install rear pinion bearing cup with Installer C-4310 and Driver Handle C-4171.
4. Install front pinion bearing cup with Installer 8617 and Handle C-4171.





5. Install rear bearing on pinion with Installer MB-998805 and a press (Fig. 69).





6. Install pinion spacer on pinion shaft (Fig. 70).





7. Install new collapsible preload spacer on pinion shaft (Fig. 71) and install pinion gear into the housing.
8. Install front pinion bearing into housing with Installer 9548.





9. Apply a light coating of gear lubricant on the lip of pinion seal and install seal with Installer 9276 (Fig. 72).
10. Hold pinion flange with Flange Wrench C-3281.
11. Screw on the new collared nut.
12. Tighten collar nut carefully to a torque to rotate of 2.5-3 Nm (22-27 in. lbs.).





13. Cut the collar of the tightened collared nut (Fig. 73).





14. Bend collar so it touches the wall of the slot in the pinion shaft (Fig. 74).
15. Invert differential case and start two ring gear bolts. This will provide case-to-ring gear bolt hole alignment.





16. Invert differential case in the vise and install new ring gear bolts and alternately tighten to 180 Nm (133 ft. lbs.) (Fig. 75)

CAUTION: Do not reuse ring gear bolts, the bolts can fracture causing extensive damage. Failure to heed caution may result in damage.

17. Install differential in axle housing and verify gear mesh and contact pattern.
