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
and driven pinion as a set.
3. CHECK RING GEAR BACKLASH
Using a dial indicator, measure the ring gear backlash. Backlash: 0.13 −0.18 mm (0.0051 −0.0071 in.)
If the backlash is not within the specification, adjust the side
bearing preload or repair as necessary.
4. MEASURE DRIVE PINION PRELOAD
Using a torque wrench, measure the preload of backlash be-
tween the drive pinion and ring gear. Preload (at starting):
0.5 − 0.8 N·m (5 − 8 kgf·cm, 4.3 − 6.9 in.·lbf)
5. CHECK TOTAL PRELOAD
Using a torque wrench, measure the preload. Total preload (at starting):
Drive pinion preload plus
0.4 − 0.6 N·m (4 − 6 kgf·cm, 3.5 − 5.2 in.·lbf)
If necessary, disassemble and inspect the differential.

6. w/o DIFFERENTIAL LOCK:
CHECK SIDE GEAR BACKLASH
Using a dial indicator, measure the side gear backlash with
holding one pinion gear toward the case.
Backlash: 0.05 − 0.20 mm (0.0020 − 0.0079 in.)
If the backlash is not within the specification, install the correct
thrust washers (See page .SA−35 ).
7. CHECK TOOTH CONTACT BETWEEN RING GEAR AND DRIVE PINION (See page SA−35 )
8. w/ DIFFERENTIAL LOCK: REMOVE ACTUATOR
(a) Remove the bolt and actuator from the differential carrier.
(b) Remove the O−ring.
9. w/ DIFFERENTIAL LOCK: REMOVE INDICATOR SWITCH
Remove the indicator switch and gasket.
10. w/ DIFFERENTIAL LOCK:
REMOVE SHIFT FORK SHAFT
(a) Using a hexagon wrench, remove the 2 straight screw plugs.
(b) Remove the spring seat, compression spring and ball.
(c) Using a pin punch and hammer , remove the slotted spring
pin.
(d) Remove the 2 bolts from the shaft retainer.
(e) Using a plastic hammer, tap out the shaft retainer.
(f) Remove the shift fork shaft.
HINT:
Pull out the shift fork shaft with a screwdriver turned round.
