Differential Carrier Assembly - Assemble^ Tools Required
- J 42178 Differential Carrier Gear Alignment Arbors
1. Place the differential carrier on the J 42178 clamped in the vice, with the ring gear flange downwards.
2. Install the counterpiece of the J 42178 into the opposing differential carrier bore (1).
3. Install a NEW differential pinion gear retaining ring (1) into the differential carrier (2).
4. Thoroughly clean all the components.
5. Place the shims on the differential side gears.
5.1. Coat the gears with rear axle lubricant.
5.2. Coat the shims with rear axle lubricant.
5.3. Install the thinner (conical) washer toward the differential side gear (1).
5.4. Install the thicker shim (with notches around the outer edge) toward the carrier.
6. Place the differential side gears with the previously installed shims into the differential carrier and onto both of the pieces of the J42178.
7. Lubricate with gear lubricant and engage the differential pinion gears (2) and engage the conical washers (1) with the differential side gears. Align them so that they are exactly opposite each other in the carrier window.
8. Move the differential pinion gear conical washers (1) forward in the intended rotational direction so that they will lead the pinion gears (2) into the mounting position.
9. Use a ratchet to rotate the J 42178 in order to draw the pinion gears and conical washers into position.
Use a small hammer and drift to assist the washers into position, if necessary.
10. Use a dead blow hammer to drive the differential pinion gear shaft (1) into the carrier bore (2) after aligning the differential pinion gears and washers with the pinion gear shaft bores.
Important: Ensure that the retaining ring remains centered in the carrier bore while driving in the pinion gear shaft.
11. Mount a torque wrench to the J42178.
12. Inspect for proper pinion rotating torque and proper side gear rotating torque.
^ 15 - 30 Nm (11 - 22 ft. lbs.).
13. Heat the ring gear to approximately 100°C (212°F).
Important: Do NOT overheat the ring gear. Damage to the ring gear may occur.
14. Install the ring gear onto the differential carrier.
Notice: Refer to Fastener Notice in Service Precautions.
15. Install NEW ring gear bolts. Tighten The ring gear bolts must be torqued in the sequence shown to 115 Nm (85 ft. lbs.).
