Ring and Pinion
Rear Axle - 267RBI / PINION GEAR/RING GEAR/ TONE RINGREMOVAL
NOTE: The ring and pinion gears are service in a matched set. Do not replace the ring gear without replacing the matched pinion gear.
1. Remove differential from axle housing.
2. Place differential case in a vise with soft metal jaw protectors. (Fig. 46)
3. Remove bolts holding ring gear to differential case.
4. Drive ring gear from differential case with a soft hammer (Fig. 46).
5. Remove exciter ring from the differential case with a brass drift and a hammer.
6. Mark pinion yoke and propeller shaft for installation alignment.
7. Disconnect propeller shaft from pinion yoke. Tie propeller shaft to underbody.
8. Hold pinion yoke with Yoke Holder 6719A and remove pinion yoke nut and washer.
9. Remove pinion yoke from pinion with Remover C-452 and Wrench C-3281 (Fig. 47).
10. Remove pinion gear from housing (Fig. 48).
11. Remove pinion seal with a slide hammer or pry bar.
12. Remove oil slinger, if equipped, and the front pinion bearing.
13. Remove front pinion bearing cup with Remover D-158 and Handle C-4171 (Fig. 49).
14. Remove rear bearing cup with Remover D-162 and Handle C-4171 (Fig. 50).
15. Remove rear bearing from the pinion with Puller/Press C-293-PA and Adapters C-293-37 (Fig. 51).
16. Remove pinion depth shims from the pinion gear shaft and record thickness of the shims.
INSTALLATION
1. Apply Mopar Door Ease stick lubricant or equivalent to the outside surface of bearing cups.
2. Install rear pinion bearing cup with Installer C-lll and Handle C-4171 (Fig. 52) and verify cup is seated.
3. Install front pinion bearing cup with Installer D-146 and Handle C-4171 (Fig. 53) and verify cup is seated.
4. Install pinion front bearing and oil slinger, if equipped. Apply a light coating of gear lubricant on the lip of pinion seal.
5. Install a new pinion seal with an appropriate installer (Fig. 54).
NOTE: Pinion depth shims are placed between the rear pinion bearing cone and pinion gear to achieve proper ring and pinion gear mesh. If ring and pinion gears are reused, the pinion depth shim should not require replacement. If the ring and pinion gears are replaced refer to Adjustments (Pinion Gear Depth) to select the proper thickness shim.
6. Place the proper thickness pinion depth shim on the pinion gear.
7. Install rear bearing and oil slinger, if equipped on the pinion gear with Installer C-3095-A and a press (Fig. 55).
8. Install original solid shims on pinion gears.
9. Install yoke with Installer C-3718 and Yoke Holder 6719A (Fig. 56).
10. Install the yoke washer and new nut on the pinion gear. Tighten the nut to 298 - 380 Nm (220 - 280 ft. lbs.).
11. Check bearing rotating torque with an inch pound torque wrench (Fig. 57). Pinion rotating torque should be:
Original Bearings: 1 to 3 Nm (10 to 20 inch lbs.).
New Bearings: 2.3 to 5.1 Nm (20 to 45 inch lbs.).
12. If rotating torque is less than the desired rotating torque, remove the pinion yoke and decrease the thickness of the solid shim pack if greater increase shim pack. Changing the shim pack thickness by 0.025 mm (0.001 inch) will change the rotating torque approximately 0.9 Nm (8 inch lbs.).
13. Invert the differential case.
14. Position exciter ring on differential case.
15. Using a brass drift, slowly and evenly tap the exciter ring into position.
16. Invert differential case and start two ring gear bolts. This will provide case-to-ring gear bolt hole alignment.
17. Invert the differential case in the vise.
18. Install new ring gear bolts and alternately tighten to 176 Nm (130 ft. lbs.) (Fig. 58).
CAUTION: Never reuse the ring gear bolts. The bolts can fracture causing extensive damage.
19. Install differential in housing and verify gear mesh and contact pattern.
20. Install differential cover and fill with gear lubricant.
