ings. Check that the right and left outer races are not inter-
changed.
(b) Install the differential case onto the carrier and tighten the
adjusting nut just to where there is no play in the bearings.
(c) Using a dial indicator, measure the ring gear runout.
Maximum runout: 0.05 mm (0.0020 in.)
(d) Remove the differential case.
7. INSTALL DRIVE PINION FRONT AND REAR BEARING

09954-03010, 09955-03030, 09956-03040)
(d) Using SST to hold the flange and adjust the drive pinion
preload by tightening the companion flange nut.
SST 09330-00021
NOTICE:
Coat the nut and screw of the drive pinon with gear oil.
As there is no spacer, tighten the nut a little at a time,
being careful not to overtighten.
(e) Using a torque wrench, measure the preload.
Preload (at starting):
New bearing
1.3 - 1.8 N´m (13 - 19 kgf´cm, 11.5 - 15.9 in.´lbf)
Reused bearing
0.64 - 0.92 N´m (6.5 - 9.4 kgf´cm, 5.7 - 8.1 in.´lbf)
HINT:
Measure the total preload after turning the bearing clockwise
and counterclockwise several times to make the bearing
smooth.
10. INSTALL DIFFERENTIAL CASE IN CARRIER
(a) Place the 2 bearing outer races on their respective bear-
ings. Make sure that the right and left outer races are not
interchanged.
(b) Install the differential case in the carrier.
HINT:
Make sure that there is backlash between the ring gear and
drive pinion.
11. INSTALL ADJUSTING NUTS
Install the 2 adjusting nuts on the carrier, making sure the nuts
are engaged properly.

12. INSTALL BEARING CAPS
Align the matchmarks on the bearing cap and carrier. Screw in
the 2 bearing cap bolts 2 or 3 turns and press down the bearing
cap by hand.
HINT:
If the bearing cap does not fit tightly on the carrier, the adjusting
nuts are not engaged properly. Reinstall the adjusting nuts if
necessary.
13. ADJUST SIDE BEARING PRELOAD
(a) Torque the 4 bolts.
Torque: 83 N´m (850 kgf´cm, 61 ft´lbf)
(b) Then loosen them to the point where the adjusting nuts
can be turned by SST.
SST 09504-0001 1
(c) Tighten the 4 bolts.
Torque: 9.8 N´m (100 kgf´cm, 7 ft´lbf)
(d) Using SST, torque the adjusting nut on the ring gear side
until the ring gear has a backlash of about 0.2 mm (0.008
in.).
(e) While turning the ring gear, use the SST to fully tighten the
adjusting nut on the drive pinion side. After the bearings
are settled, loosen the adjusting nut on the drive pinion
side.
(f) Place a dial indicator on the top of the adjusting nut on the
ring gear side.
(g) Adjust the side bearing to zero preload by tightening the
other adjusting nut until the pointer on the indicator be-
gins to move.

(h) Using the SST, torque the adjusting nut 1 - 1.5 notches
from the zero preload position.
(i) Using a dial indicator, adjust the ring gear backlash until
it is within the specified value.
Backlash: 0.13 - 0.18 mm (0.0051 - 0.0071 in.)
HINT:
The backlash is adjusted by turning the right and left adjusting
nuts equal amounts. For example, loosen the nut on the left
side 1 notch and torque the nut on the right side 1 notch.
(j) Torque the 4 bolts.
Torque: 83 N´m (850 kgf´cm, 61 ft´lbf)
(k) After rotating the ring gear 5 turns or more, recheck the
ring gear backlash.
Backlash: 0.13 - 0.18 mm (0.0051 - 0.0071 in.)
14. MEASURE TOTAL PRELOAD
Using a torque wrench, measure the preload with the teeth of
the drive pinion and ring gear in contact.
Preload (at starting):
Drive pinion preload plus
0.38 - 0.63 N´m (3.9 - 6.5 kgf´cm, 3.3 - 5.6 in.´lbf)
15. INSPECT TOOTH CONTACT BETWEEN RING GEAR
AND DRIVE PINION
(a) Coat 3 or 4 teeth at 3 different positions on the ring gear
with red lead primer.
(b) Turn the companion flange, in both directions to inspect
the ring gear for proper tooth contact.
