Disassembly
1. WARNING: If equipped with fire suppression system, depower the system. For important safety warnings and procedures, refer to Fire Suppression System.
Remove the differential assembly from the differential housing.
2. Remove the differential ring gear bolts.
3. CAUTION: Do not damage the bolt hole threads.
Insert a punch in the bolt holes and drive off the differential ring gear.
4. Using the special tools, remove the differential bearings.
5. Remove the differential pinion shaft bolt and remove the differential pinion shaft.
6. WARNING: Due to the spring tension, use care when removing the differential clutch spring.
Remove the differential clutch spring.
7. Remove the differential gears.
1 Remove the 2 differential pinion gears.
2 Remove the 2 differential side gears.
3 Remove the 2 differential pinion thrust washers.
8. CAUTION: Keep the differential clutch packs in order. Do not mix them. Always reassemble them in the same sequence.
Separate the differential clutch packs and shims from the differential side gears and tag them "right" and "left."
^ Clean and inspect the remaining differential components for wear and damage and install new parts as necessary.
9. CAUTION: Do not use acids or solvents when cleaning the differential clutch packs. Wipe the components only with a clean, lint-free cloth.
Clean and inspect the differential clutch packs for wear and damage and install new parts as necessary.
Assembly
1. CAUTION: 118 ml (4 oz.) of the Additive Friction Modifier must be used in the axle.
Using the modifier, lubricate each steel clutch plate and soak all the friction plates for no less than 15 minutes.
2. CAUTION: Do not mix the clutch plates, clutch discs or shim from one side with the other.
Assemble the differential clutch packs (without the shims) on their respective differential side gear.
3. CAUTION: Use the correct mandrel with the special tool.
Place the base portion of the special tool in a vise. Install the differential side gear and differential clutch pack (without the shim) on the tool.
4. Position the special tool hand-tight on top of the differential clutch pack.
5. Install the special tool over the disc and differential clutch pack.
6. Install the nut.
^ Tighten to 6.7 Nm (60 inch lbs.).
7. Select and insert the thickest feeler gauge blade that will enter between the tool and the differential clutch pack. The reading will be the thickness of the new clutch shim.
Selective Shims:
8. Remove the special tool from the differential clutch pack and differential side gear assembly.
9. Install the shim(s) on the differential clutch pack and differential side gear assembly.
10. Install the differential side gear assemblies in the differential case.
11. Install the differential pinion gear and differential pinion thrust washer assemblies in the differential case.
12. Using a soft-faced hammer, install the differential clutch spring.
13. Install the differential pinion shaft and install a new bolt finger-tight.
14. Mount the differential case and the special tool in a vise. Using the special tool, check the torque necessary to rotate one differential side gear.
^ If reusing the original clutch plates, the initial minimum break-away torque must be no less than the specification. The minimum rotating torque necessary to keep the differential side gear turning with new clutch plates may vary.
15. Using the special tool, install the differential bearings.
16. Position the differential ring gear and the differential case. Align the bolt holes by starting 2 bolts through the holes in the differential case and the differential ring gear. Press the differential ring gear on the differential case.
17. NOTE: Clean bolt threads to make sure the bolts are free of foreign material.
Apply stud and bearing mount to the differential ring gear bolt threads and install the bolts.
^ Install new bolts.
- Tighten to 105 Nm (77 ft. lbs.).
18. Install the differential assembly.
19. WARNING: If equipped with fire suppression system, repower the system. For important safety warnings and procedures, refer to Fire Suppression System.
If equipped with fire suppression system, repower the system.
