DISASSEMBLY
1. CHECK RUNOUT OF COMPANION FLANGE
Using a dial indicator, measure the vertical and lateral runout of
the companion flange. Maximum runout: 0.10 mm (0.0039 in.)
2. CHECK RING GEAR RUNOUT
Using a dial indicator, measure the ring gear runout. Maximum runout: 0.10 mm (0.0039 in.)
If the runout is greater than the maximum, replace the ring gear.
3. CHECK RING GEAR BACKLASH
Using a dial indicator, measure the ring gear backlash. Backlash: 0.15 − 0.20 mm (0.0059 − 0.0079 in.)
HINT:
Perform the measurements at 3 or more positions around the
circumference of the ring gear.
If the backlash is not within the specification, adjust the side
bearing preload or repair as necessary.
4. MEASURE DRIVE PINION PRELOAD
(a) Using a torque wrench, measure the preload of backlash between the drive pinion and ring gear.
Preload (at starting):
0.7 − 1.0 N·m (7 − 10 kgf·cm, 6.1 − 8.7 in.·lbf)
(b) Using a torque wrench, measure the preload. Total preload (at starting):
Drive pinion preload plus
w/o Differential lock
0.4 − 0.6 N·m (4 − 6 kgf·cm, 3.5 − 5.2 in.·lbf)
w/ differential lock
0.3 − 0.7 N·m (3 − 7 kgf·cm, 2.6 − 6.1 in.·lbf)
If necessary, disassemble and inspect the differential.

5. CHECK SIDE GEAR BACKLASH
Using a dial indicator, measure the side gear backlash with
holding one pinion gear toward the case.
Backlash: 0.02 − 0.20 mm (0.0008 − 0.0079 in.)
If the backlash is not within the specification, install the correct
thrust washers (See page SA−87).
6. CHECK TOOTH CONTACT BETWEEN RING GEAR
AND DRIVE PINION (See page SA−35 )
7. w/ DIFFERENTIAL LOCK: REMOVE INDICATOR SWITCH
Remove the indicator switch and gasket.
8. w/ DIFFERENTIAL LOCK: REMOVE COVER
(a) Remove the 3 bolts.
(b) Using a brass bar and hammer, tap on the cover to re- move it.
9. w/ DIFFERENTIAL LOCK: REMOVE SLEEVE
(a) Remove the 4 bolts.
(b) Using a plastic hammer, tap the actuator.
(c) Remove the actuator and sleeve.
10. w/ DIFFERENTIAL LOCK: REMOVE ACTUATOR AND SHIFT FORK AND SHAFT
(a) Remove the shift fork shaft bolt.
(b) Pull out the actuator and remove the shift fork.
11. REMOVE COMPANION FLANGE
(a) Using a chisel and hammer, unstick the nut.
(b) Using SST to hold the flange, remove the nut and plate washer.

12. REMOVE OIL SEAL AND OIL SLINGER
(a) Using SST, remove the oil seal from the dif ferential carrier.
SST 09308−10010
(b) Remove the oil slinger.
13. REMOVE FRONT BEARING
Using SST, remove the front bearing from the drive pinion. SST 09556−22010
If the front bearing is damaged or worn, replace the bearing.
14. w/o DIFFERENTIAL LOCK: REMOVE DIFFERENTIAL CASE ASSEMBLY
(a) Place matchmarks on the bearing cap and dif ferential car-
rier.
(b) Remove the 2 adjusting nut locks.
HINT:
