DISASSEMBLY OF DIFFERENTIAL
(See page RA-281
NOTE: lf the differential is noisy, perform the following
pre-inspection before disassembly to determine the cause.
lf the differential has severe problems, disassemble and
repair as necessary.
1. CHECK RING GEAR RUNOUT
Maximum runout: 0.07 mm (O.OO28 in.l
lf the runout is exceeds maximum, replace the ring gear.
2. CHECK RING GEAR BACKLASH
Backlash: 0.10 - 0.15 mm (O.OO39 - O.OO59 in.)
lf the backlash is not within specification, adjust the side
bearing preload or repair as necessary. (See step 5 on
page RA-36)
3, INSPECT TOOTH CONTACT BETWEEN RING GEAR
AND DRIVE PINION (See step 6 on page RA-38)
Note the tooth contacting position.
4. CHECK SIDE GEAR BACKLASH
Measure the side gear backlash while holding one pinion
gear toward the case.
Standard backlash:
O.OZ - 0.15 mm (0.0008 - 0.0059 in.)
lf the backlash is not within specification, install the cor-
rect thrust washers.
5. CHECK DRIVE PINION PRELOAD
Using a torque wrench, measure the preload of the back-
lash between the drive pinion and ring gear.
Preload: 4-7 kg-cm
{3.5 - 6.1 in.-lb, 0.4 - O.7 N'm}
6. CHECK TOTAL PRELOAD
Using a torque wrench, measure the total preload.
Total preload:
In addition to drive pinion preload
2 - 4 kg-cm $.7 ' 3.5 in.-lb, O.2 - O.4 N'm)
Page 543 of 885

REAR AXIE AND SUSPENSION - Differential (4WD)RA-35
(l) Clean the contact surface of the ring gear with clean-
ing solvent.
(m) Then quickly install the ring gear on the differential
case.
(n) Coat the ring gear mount bolts with gear oil.
(o) Install new lock plates and the mount bolts. Tighten
the mount bolts uniformly and a little at a time. Tor-
que the bolts.
Torque: 985 kg-cm (71 ft-lb, 97 N.m)
(p) Check the ring gear runout.
Maximum runout: 0.07 mm (0.028 in.)
(q) Stake the lock plate.
NOTE: Stake one claw flush with the flat surface of the
nut. For the claw contacting the protruding portion of the
nut, stake (bend) only the half on the tightening side.
ASSEMBLY OF DIFFERENTIAL
(See page RA-28)
1. TEMPORARILY ADJUST DRIVE PINION PRELOAD
(a) lnstall the following parts:
o Drive pinion
o Front bearing
NOTE: Assemble the spacer, oil slinger and oil seal after
adjusting the gear contact pattern.
(b) Using SST, install the companion flange.
ssT 09557-22022
(c) Adjust the drive pinion preload by tightening the
companion flange nut.
Using SST to hold the flange, tighten the nut.
ssT 09330-00020
CAUTION: As there is no spacer, taghten a little at a
time, being careful not to overtighten.

(d) Using a torque wrench, measure the preload.
Preload: New bearing 6.5 - 12.5 kg-cm
(5.6 - 1O.9 in.-lb)(0.6 - 1.2 N.ml
Reused bearing 4 - 7 kg-cm(3.5 - 6.1 in.-lb)(0.4 - 0.7 N.ml
2. INSTALL DIFFERENTIAL CASE IN CARRIER
(d Place the bearing outer races on their respective
bearings. Make sure the left and right outer races are
not interchanged.
(b) Install the case in the carrier.
3. INSTALL ADJUSTING NUTS
Install the adjusting nuts on their respective carrier, mak-
ing sure they are threaded properly.
NOTE: Make sure that there is backlash between the ring
gear and drive pinion.
4, INSTALL BEARING CAPS
Align the matcfimarks on the cap and carrier. Screw in the
two bearing cap bolts two or three turns and press down
the bearing cap by hand.
NOTE: lf the bearing cap does not fit tightly on the car-
rier, the adjusting nut threads are not threaded properly.
Reinstall adjusting nuts if necessary.
5. ADJUST SIDE BEARING PRELOAD
(a) Tighten the bearing cap bolts until the spring
washers are slightly compressed.
(b) Using SST, tighten the adjusting nut on the ring gear
side until the ring gear has a backlash of about 0.2
mm (0.0O8 in.).

Page 545 of 885
REAR AXLE AND SUSPENSION - Differential (4WD)RA.37
(c) Using SST, firmly tighten the adjusting nut on the
drive pinion side.
ssr o9504-ooo1 1
(d) Check the ring gear backlash.
lf tightening the adjusting nut creates ring gear backlash,
loosen the nut so that backlash is eliminated.
(e) Place a dial indicator on the top of the bearing cap on
the ring gear side.
(f) Adjust the side bearing for zero preload by tightening
the other adjusting nut until the pointer on the indica-
tor begins to move.
(g) Tighten the adjusting nut 1 - 1llz notches from the
zero preload position.
(h) Using a dial indicator, adjust the ring gear backlash
until it is within specification.
Backlash: 0.10 - 0,15 mm (O.OO39 - O.OO59 in.l
NOTE: The backlash is adjusted by turning the left and
right adjusting nuts equal amounts. For example, loosen
the nut on the left side one notch and tighten the nut on
the right side one notch.
(i) Torque the bearing cap bolts.
Torque: 6OO kg-cm (43 ft-lb, 59 N.ml
Page 546 of 885
RA.38REAR AXLE AND SUSPENSION - Differentiat (4WD)
(j) Recheck the ring gear backlash.
(0 Using a torque meter, measure the total preload.
Total preload:
ln addition to drive pinion preload
2 - 4 kg-cm 11.7 - 3.5 in.-lb, O.2 - 0.4 N.m)
Backlash: O.1O - O.15 mm (0.0039 - 0.O059 in.)
6. INSPECT TOOTH CONTACT BETWEEN RING GEAR
AND DRIVE PINION
(a) Coat red lead on 3 or 4 teeth at three different posi-
tions of the ring gear.
(b) Hold the companion flange firmly and rotate the ring
gear in both directions.
(d lnspect the tooth pattern.
