Disassembly Procedure
1. Remove the drain plug and drain the oil. Reinstall the drainplug.
2. Remove the axle housing cover. Notice Clean the cover and housing contact surface.
3. Remove the bearing cap bolts and remove the bearing caps. Pull out the differential carrier assembly. Notice Place alignment marks on the bearing cap not to change the caps before removal. When pulling out the differential
carrier assembly, be careful not to damage the axle housing.
4. Disassemble the parts of the differential carrier assembly.
Tightening Torque 28 - 42Nm

5. Remove the drive pinion lock nut. Disassemble the parts ofthe drive pinion.
Assembly Procedure
1. Clean the all parts and check the followings. Check the ring gear and drive pinion for wear or damage.
If damaged, replace it as set.
Check the bearing for sticks, wear, noise or turning
resistance.
Check the side gear, pinion, pinion shaft and thrust
washer for wear or damage.
Check the differential carrier for crack or wear (bearing
contact surface). Check the gear case for crack.
2. Assemble the parts of the drive pinion.
3. Assemble the parts of the differential carrier.
Tightening Torque of The Pinion Lock Nut 240 - 310 Nm
Tightening Torque of The
Ring Gear Bolts 75 - 90 Nm

4. Measure backlash of the side gear and pinion gear.
Specified Value 0 - 0.05 mm
5. Install the differential carrier assembly into the axle housing.
Tightening Torque of The Bearing Cap Bolts 48 - 69 Nm
Notice Be careful no to change the caps. Be sure to keep the original position of the caps.
6. Measure backlash of the drive pinion and ring gear.
7. Install the axle housing cover.
Specified Value 0.13 - 0.20 mm
Tightening Torque 39 - 46 Nm

Inspection of Ring Gear Tooth Contact Pattern Normal Contact Apply gear-marking compound (prussian blue / red lead) on the ring gear teeth. Rotate the ring gear and check the tooth contact pattern. Abnormal Contact
Tooth Contact pattern Possible CauseRemedy
1. Heel Contact
2. Toe Contact
3. Face Contact
4. Flank ContactInsufficient backlash (little)

Tooth can be damaged or broken under heavy load
Excessive backlash (much)
Drive pinion shaft is apart from the ring gear
Noise can be occurred
Insufficient backlash (much)
Gear contacts on the low flank
Gear can be damaged orworn
Noise can be occurred Adjust backlash(Decrease backlash)

Select proper shim(s) to move the drive pinion toward the ring gear (toward toe)
Adjust backlash(Increase backlash)
Select proper shim(s) to move the drive pinion against the ring gear (toward heel)
Adjust backlash(Increase pinion shim)
Move the drive pinion toward the ring gear (toward center of ring gear)
Adjust backlash(Decrease pinion shim)
Move the ring gear toward the drive pinion (toward ring gear center line)
Excessive backlash (little)

Noise can be occurred
