19. ADJUST DRIVE PINION PRELOAD
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
1.3 ± 1.9 N´m (13 ± 19 kgf´cm, 11.4 ± 16.7
in.´lbf)
Reused bearing
0.8 ± 1.1 N´m (8 ± 11 kgf´cm, 7.0 ± 9.7 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 a force of 13 N´m (130 kgf´cm, 9 ft´lbf) until the specified
preload is reached.
Torque: 451 N´m (4,600 kgf´cm, 333 ft´lbf) or less
If the maximum torque is exceeded while retightening the nut,
replace the bearing spacer and repeat the preload procedure.
Do not loosen the pinion nut to reduce the preload.
20. CHECK TOTAL PRELOAD
Using a torque wrench, measure the total 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)
21. CHECK RING GEAR BACKLASH
Using a dial indicator, measure the ring gear backlash.
Backlash: 0.13 ± 0.18 mm (0.0051 ± 0.0071 in.)
22. RECHECK TOOTH CONTACT BETWEEN RING GEAR
AND DRIVE PINION (See step 13.)
23. CHECK COMPANION FLANGE RUNOUT
(See page SA±113)
24. STAKE DRIVE PINION NUT

INSTALLATION
1. INSTALL DIFFERENTIAL CARRIER ASSEMBLY
(a) Install a new gasket.
(b) Install the differential carrier assembly with the 10 washers and nuts.
NOTICE:
Be careful not to damage the installation surface.
Torque: 73 N´m (740 kgf´cm, 54 ft´lbf)
2. CONNECT REAR PROPELLER SHAFT
2WD: See page PR±5
4WD: See page PR±9
3. INSTALL REAR AXLE SHAFTS (See page SA±102)
4. FILL DIFFERENTIAL WITH HYPOID GEAR OIL (See page SA±105)

REMOVAL
NOTICE:

Do not extend the pneumatic cylinder by itself. If the
cylinder is fully extended, it cannot be reused.

Do not replenish the pneumatic cylinder by itself with
air.

Do not remove the pneumatic cylinder with air in it.

If reusing the pneumatic cylinder, replace the 2 O±
rings, plate and connector No.2 with new ones.

When installing the pneumatic cylinder, keep the cyl-
inder length 260 mm (10.236 in.) or less.
1. BLEED AIR (See page SA±153)
HINT:
Disconnect the one touch air connector of the height control
valve and bleed the air.
2. REMOVE REAR PNEUMATIC CYLINDER
(a) Jack up the vehicle and support the frame with safety
stands.
NOTICE:

Do the work with the rear axle assy lowered.

Do the work with the shock absorber installed.
(b) Disconnect the height control tube.
(c) Remove the clip on the upper side of the rear pneumatic
cylinder.
HINT:

If the clip cannot be easily removed, thread a wire through
the hole to pull it.

When installing the clip, make sure that the center pin on
the upper side of the rear pneumatic cylinder is in the
slotted hole of the frame.
(d) Remove the rear pneumatic cylinder.

HINT:
Perform the following before installation.
When using safety stands and jack:
(1) Jack up the rear axle until the bottom of the rear
pneumatic cylinder touches the rear axle and fit the
seating pin on the lower side of the rear pneumatic
cylinder into the rear axle.
NOTICE:

Do not extend the rear pneumatic cylinder in order to
fit the seating pin into the hole.

Make sure that the seating pin on the lower side of the
rear pneumatic cylinder fits in the hole in the rear
axle.
(2) Remove the safety stands with care not to extend
the rear pneumatic cylinder when jacking down the
vehicle till it sits on the ground.
NOTICE:
Make sure that the diaphragm (rubber part) of the pneumat-
ic cylinder is not deformed.
(3) Start the engine and replenish the rear pneumatic
cylinder with air.
(e) When using a swing arm type lift:
(1) Lower the vehicle till the tires hit the ground, and
continue lowering slowly until the bottom of the rear
pneumatic cylinder touches the rear axle.
(2) Align the seating pin on the cylinder with the hole in
the rear axle and install the rear pneumatic cylinder
on the rear axle.
NOTICE:

Do not extend the rear pneumatic cylinder by lifting
up the rear axle housing after fitting the seating pin.

Make sure that the diaphragm (rubber part) of the
pneumatic cylinder is not deformed.
(3) Lower the lift carefully so as not to extend the rear
pneumatic cylinder.
NOTICE:
Make sure that the diaphragm (rubber part) of the pneumat-
ic cylinder is not deformed.
(4) Start the engine and replenish the rear pneumatic
cylinder with air.
