REASSEMBLY
1. w/o DIFFERENTIAL LOCK: ASSEMBLE DIFFERENTIAL CASE
(a) Apply all of the sliding and rotating sufaces with gear oil.
(b) Install the 2 thrust washers and side gears. Using the table below, select the thrust washers which will
ensure that the backlash is within the specification.
Try to select washers of the same size for both sides.
Thrust washer thickness
Thickness mm (in.)Thickness mm (in.)
1.60 (0.063).80 (0.071)
1.70 (0.067)1−
(c) Install the 2 side gears with the side gears thrust washers,
4 pinion gears, pinion gear thrust washers and pinion
shaft.
HINT:
Align the hole for the pinion shaft with the case hole.
(d) 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 a thrust
washer of different thickness.
(e) Using a pin punch and hammer, install the straight pin through the holes in the dif ferential case and pinion shaft.
(f) Using a chisel and hammer, stake the out side of the dif- ferential case pin hole.
2. w/ DIFFERENTIAL LOCK: INSPECT SLEEVE
(a) Install the sleeve to the differential case (LH) and check
it moves smoothly.
(b) Install the sleeve to the side gear check it moves smooth-
ly.

3. w/ DIFFERENTIAL LOCK:
MEASURE CLEARANCE OF SHIFT FORK AND
SLEEVE
Using a feeler gauge, measure the clearance between the shift
fork and sleeve. Clearance:
0.15 − 0.35 mm (0.006 − 0.014 in.)
4. w/ DIFFERENTIAL LOCK: ASSEMBLE DIFFERENTIAL CASE
(a) Apply all of the sliding and rotating sufaces with gear oil.
(b) Install the side gear thrust washer to the side gear.
(c) Install the side gear to the RH case.
(d) Install the 4 pinion gears and pinion gear thrust washers to the spider.
(e) Install the pinion gear with the spider to the RH case.
(f) Using a dial indicator, holding the side gear and spider and measure the side gear backlash.
Backlash: 0.05 − 0.20 mm (0.0020 − 0.0079 in.)
HINT:
Measure at all 4 locations.
Measure the backlash at the RH case and at the LH case.
If the backlash is not within the specification, install a thrust
washer of a different thickness. Thrust washer thickness
Thickness mm (in.)Thickness mm (in.)
0.9 (0.035)1.2 (0.047)
1.0 (0.039)1.3 (0.051)
1.1 (0.043)−
(g) Install the side gear and side gear thrust washer to the RH
case.
(h) Install the pinion gears and spider to the RH case.
(i) Install the side gear and side gear thrust washer to the RH
case.
(j) Align the matchmarks on the LH and RH cases.
(k) Torque the 8 bolts uniformly, a little at a time. Torque: 47 N·m (480 kgf·cm, 35 ft·lbf)
