Using SST to hold the flange, tighten the nut.

HINT:
Adjust the drive pinion preload by tightening the companion
flange nut.

SST

NOTICE:
As there is no spacer, tighten the nut a little at a time and
be careful not to overtighten it.

(e)

Using a torque wrench, measure the preload of the drive
pinion using the backlash between the drive pinion and
ring gear.
Preload (at starting):
New bearing
1.1 – 1.8 N·m (11 – 18 kgf·cm, 9.7 – 15.9 in.·lbf)
Reused bearing
0.5 – 0.9 N·m (5 – 9 kgf·cm, 4.4 – 8.0 in.·lbf)

ADJUST RING GEAR BACKLASH

(a)

Install the side bearing retainer with the 10 bolts.
Torque: 69 N·m (700 kgf·cm, 51 ft·lbf)

HINT:
Rotate the ring gear several times to make the bearing fit.

(b)

Using SST and a dial indicator, measure the ring gear
backlash.
SST

09564–32011

Backlash: 0.1 – 0.18 mm (0.0039 – 0.0071 in.)

If the backlash is not within the specified value, adjust it by ei-
ther increasing or decreasing the thickness of plate washers on
both sides by an equal amount.
HINT:
There should be no clearance between the plate washer and
case. Ensure that there is ring gear backlash.

MEASURE 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 0.4 – 0.6 N·m (4 – 6 kgf·cm,
3.5 – 5.2 in.·lbf)

13.

INSPECT TOOTH CONTACT BETWEEN RING GEAR
AND DRIVE PINION

(a)

Remove the 10 bolts, side bearing retainer and differen-
tial case.

(b)

Coat 3 or 4 teeth at three different positions on the ring
gear with red lead primer.

(c)

Install the differential case and side bearing retainer with
the 10 bolts.
Torque: 69 N·m (700 kgf·cm, 51 ft·lbf)

(d)

Hold the companion flange firmly and rotate the ring gear
in both directions.

(e)

Remove the 10 bolts, side bearing retainer and differen-
tial case.

(f)

Inspect the tooth contact pattern.

ADJUST DRIVE PINION PRELOAD

Using a torque wrench, measure the preload of the drive pinion
using the backlash between the drive pinion and the ring gear.

Preload (at starting):
New bearing
1.2 – 1.9 N·m (12 – 19 kgf·cm, 10.4 – 16.5 in.·lbf)
Reused bearing
0.6 – 1.0 N·m (6 – 10 kgf·cm, 5.2 – 8.7 in.·lbf)

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

Torque: 223 N·m (2,275 kgf·cm, 165 ft·lbf) or less

If the torque is exceeded the maximum while retightening the
nut, replace the bearing spacer and repeat the preload adjust-
ing procedure. Do not loosen the nut to reduce the preload.
