AXLE AND DIFFERENTIAL: REAR DIFFERENTIAL CARRIER ASSEMBLY (w/ Differential Lock): REASSEMBLY - (Continued)

11. INSPECT AND ADJUST DIFFERENTIAL RING GEAR AND DIFFERENTIAL DRIVE PINION BACKLASH





(a) Align the matchmarks on the cap and carrier.





(b) Install the right and left bearing caps with the 4 bolts.

Torque : 103 Nm (1049 kgf-cm, 76 ft-lbf)

HINT
If the bearing cap does not fit tightly onto the carrier, the adjusting nuts are not threaded properly.

Reinstall the adjusting nuts if necessary.

(c) Tighten the 4 bearing cap bolts to the specified torque, and then loosen them to the point where the adjusting nuts can be turned by SST.





Torque : 103 Nm (1049 kgf-cm, 76 ft-lbf)





(d) Using SST, tighten the adjusting nut on the ring gear side until the ring gear has a backlash of about 0.2 mm (0.008 in.).

SST : 09960-10010

09962-01000

09963-00700

(e) While turning the ring gear, use SST to tighten the adjusting nut on the drive pinion side.









HINT
After the bearings have settled, loosen the adjusting nut on the drive pinion side.

(f) Using SST, tighten the adjusting nut 1 to 1.5 notches from the 0 preload position.

SST : 09504-00011

(g) Using a dial indicator, adjust the ring gear backlash until it is within the specification.





Standard backlash (reference):

0.10 to 0.20 mm (0.00394 to 0.00787 in.)

HINT
* The backlash is adjusted by turning the left and right adjusting nuts an equal amount. For example, loosen the nut on the right side one notch and loosen the nut on the left side one notch.
* Perform the measurement at 3 or more positions around the circumference of the ring gear.
(h) Tighten the bearing cap bolts.





Torque : 103 Nm (1049 kgf-cm, 76 ft-lbf)





12. INSPECT TOTAL PRELOAD





(a) Using a torque wrench, measure the preload with the teeth of the drive pinion and ring gear in contact.

Standard total preload (at starting):

Drive pinion preload plus 0.20 to 0.40 N*m (2.0 to 4.1 kgf*cm, 1.8 to 3.5 in.*lbf)

(b) If necessary, disassemble and inspect the differential.

13. INSPECT TOOTH CONTACT BETWEEN RING GEAR AND DRIVE PINION





(a) Coat 3 or 4 teeth at 3 different positions on the ring gear with Prussian blue.

(b) Hold the companion flange firmly and rotate the ring gear in both directions.

(c) Inspect the tooth contact pattern.













* If the teeth are not engaged properly, use the following chart to select an appropriate washer for correction.





14. REMOVE REAR DRIVE PINION NUT





(a) Using SST to hold the drive pinion companion flange, remove the nut.

SST : 09330-00021

15. REMOVE REAR DRIVE PINION COMPANION FLANGE SUB-ASSEMBLY





(a) Using SST, remove the drive pinion companion flange.

SST : 09950-30012

09951-03010

09953-03010

09954-03010

09955-03030

09956-03040

16. REMOVE REAR DIFFERENTIAL DRIVE PINION OIL SLINGER

17. REMOVE REAR DRIVE PINION FRONT TAPERED ROLLER BEARING (INNER) Replacement

18. REMOVE REAR DRIVE PINION FRONT TAPERED ROLLER BEARING (OUTER)

19. INSTALL REAR DIFFERENTIAL DRIVE PINION BEARING SPACER





(a) Install a new bearing spacer to the drive pinion.

20. INSTALL DIFFERENTIAL OIL STORAGE RING





(a) Using SST, tap in a new oil storage ring.

SST : 09308-14010

21. INSTALL REAR DRIVE PINION FRONT TAPERED ROLLER BEARING

22. INSTALL REAR DIFFERENTIAL DRIVE PINION OIL SLINGER

23. INSTALL REAR DIFFERENTIAL CARRIER OIL SEAL





(a) Apply MP grease to the oil seal lip.

(b) Using SST and a hammer, install a new carrier oil seal.

SST : 09214-76011

Standard oil seal drive in depth:

-0.3 to 0.3 mm (-0.0118 to 0.0118 in.)





24. INSTALL REAR DRIVE PINION COMPANION FLANGE SUB-ASSEMBLY REAR





(a) Using SST, install the drive pinion companion flange to the drive pinion.

SST : 09950-30012

09951-03010

09953-03010

09954-03010

09955-03030

09956-03040

(b) Coat the threads of a new nut with hypoid gear oil.





(c) Using SST to hold the flange, tighten the nut.

SST : 09330-00021

Torque : 457 Nm (4660 kgf-cm, 337 ft-lbf or less)

25. INSPECT DRIVE PINION PRELOAD





(a) Using a torque wrench, measure the preload of the backlash between the drive pinion and ring gear.

Standard Preload (at Starting):





(b) If the preload is more than the maximum, replace the bearing spacer.

If the preload is less than the minimum, retighten the nut with 13 N*m (130 kgf*cm, 9 ft.*lbf) of torque at a time until the specified preload is reached.

Torque : 457 Nm (4660 kgf-cm, 337 ft-lbf or less)

(c) If the maximum torque is exceeded while retightening the nut, replace the bearing spacer and repeat the preload adjusting procedure.

HINT
Do not loosen the pinion nut to reduce the preload.
