If the preload is less than the specified value, retighten the nut
with a force of 13 N´m (130 kgf´cm, 9 ft´lbf) at a time until the spe-
cified preload is reached.

DISASSEMBLY
1. SET DIFFERENTIAL CARRIER TO OVERHAUL STAND
ETC.
2. 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.)
If the runout is greater than the maximum, replace the compan-
ion flange.
3. CHECK RING GEAR RUNOUT
Using a dial indicator, measure the ring gear runout.
Maximum runout: 0.05 mm (0.0020 in.)
If the runout is greater than the maximum, replace the ring gear.
4. CHECK RING GEAR BACKLASH
Using a dial indicator, while holding the drive pinion flange,
measure the ring gear backlash.
Backlash: 0.13 - 0.18 mm (0.0051 - 0.0071 in.)
HINT:
Perform the measurements at 3 or more positions around the
circumference of the ring gear.
If the backlash is not within the specified value, adjust the side
bearing preload or repair as necessary.
5. MEASURE DRIVE PINION PRELOAD
Using a torque wrench, measure the drive pinion preload using
the backlash of the drive pinion and ring gear.
Preload (at starting):
0.64 - 0.92 N´m (6.5 - 9.4 kgf´cm, 5.7 - 8.1 in.´lbf)

6. CHECK TOTAL PRELOAD
Using a torque wrench, measure the preload with the teeth of
the drive pinion and ring gear in contact.
Total preload (at starting):
Drive pinion preload plus
0.3 - 0.5 N´m (3 - 5 kgf´cm, 2.7 - 4.4 in.´lbf)
If necessary, disassemble and inspect the differential.
7. CHECK TOOTH CONTACT BETWEEN RING GEAR
AND DRIVE PINION (See page SA-127)
8. REMOVE REAR DIFF. LOCK POSITION SWITCH
Remove the rear diff. lock position switch and gasket.
9. REMOVE COVER
(a) Remove the 3 bolts.
(b) Using a brass bar and hammer, tap on the cover to re-
move it.
10. REMOVE ACTUATOR, SHIFT FORK AND SLEEVE
(a) Remove the 4 bolts.
(b) Remove the shift fork shaft bolt.
(c) Using a screwdriver, pull out the actuator and remove the

rier.
(b) Remove the 4 bolts and 2 bearing caps.
(c) Using SST and a hammer, remove the plate washers.
SST 09504-22012

tween it and the carrier.
(d) Align the matchmarks on the bearing cap and differential
carrier.
