INSTALLATION
1. INSTALL PROPELLER SHAFT
(a) Apply grease to the flexible coupling centering bushings.
Grease:
Molybdenum disulphide lithium base, NLGI No.2
(b) Install the propeller shaft from the vehicle's rear and con-
nect the transmission and differential.
NOTICE:
Support the center support bearing by hand so that the
transmission and intermediate shaft, and propeller shaft
and differential, remain in a straight line.
(c) Temporarily install the 2 center support bearing set bolts
with the adjusting washers.
HINT:
Use the adjusting washers which were removed.
(d) Align the matchmarks and connect the propeller shaft to
the transmission/differential.
(e) Install and torque the 3 bolts, washers and nuts.
NOTICE:
The bolts should be installed from the propeller shaft side.
Torque: 79 N´m (805 kgf´cm, 58 ft´lbf)
(f) If using a new propeller shaft (w/ Phasemarks):
Install the propeller shaft phasemarks and differential/
transmission phasemarks so that their respective align-
ment phasemarks match.
If the propeller shaft phasemarks and differential/trans -
mission phasemarks do not align, install the propeller
shaft and differential alignment phasemarks as close to-
gether as possible.
(g) If using a new propeller shaft (w/o Phasemarks):
Install the propeller shaft.
(h) Torque the 2 center support bearing set bolts.
Torque: 37 N´m (375 kgf´cm, 27 ft´lbf)
HINT:
Adjust the center support bearing to keep the intervals as
shown with the vehicle in the unladen condition.
Under the same condition, check if the center line of the center
support bearing is at right angles to the shaft axial direction.

(i) Using SST, tighten the adjusting nut.
SST 09922±10010
Torque: 50 N´m (515 kgf´cm, 37 ft´lbf)
HINT:
Use a torque wrench with a fulcrum length of 34.5 cm (13.6 in.).
2. INSPECT JOINT ANGLE (See page PR±12)
NOTICE:
The joint angle should by all means be checked when the
propeller shaft is removed and installed.
3. INSTALL 2 HEAT INSULATORS
(a) Install the heat insulator and torque the 4 bolts.
Torque: 5.4 N´m (55 kgf´cm, 48 in.´lbf)
(b) Install the heat insulator and torque the 6 bolts.
Torque: 5.4 N´m (55 kgf´cm, 48 in.´lbf)
4. INSTALL EXHAUST PIPE ASSEMBLY
(a) Connect the exhaust pipe assembly to the O±rings.
(b) 2JZ±GE Engine:
Install the 3 bolts, nuts and 2 gaskets to the exhaust man-
ifold. Torque the bolts.
Torque: 44 N´m (450 kgf´cm, 33 ft´lbf)
(c) 1UZ±FE Engine:
Install the 4 bolts, nuts and 2 gaskets to the exhaust man-
ifold. Torque the bolts.
Torque: 44 N´m (450 kgf´cm, 33 ft´lbf)
(d) Install the front floor center brace and torque the 2 bolts.
Torque: 7.4 N´m (75 kgf´cm, 65 in.´lbf)
(e) Connect the heated oxygen sensor.
Torque: 44 N´m (450 kgf´cm, 33 ft´lbf)
HINT:

Before installing the oxygen sensor, twist the sensor wire
counterclockwise 3 and 1/2 turns.

After installing oxygen sensor, check that the sensor wire
should not twist. If it is twisted, remove the oxygen sensor
and reinstall it.

JOINT ANGLE
INSPECTION
NOTICE:
When performing operations which involve the removal
and installation of the propeller shaft, always check the
joint angle. Make adjustments if necessary.
1. STABILIZE PROPELLER SHAFT AND DIFFERENTIAL
(a) Turn the propeller shaft several times by hand to stabilize
the center support bearing and flexible couplings.
(b) Using a jack, raise and lower the differential to stabilize
the differential mounting cushion.
2. CHECK NO.2 AND NO.3 JOINT ANGLE
(a) Using SST, measure the installation angle of the inter-
mediate shaft and propeller shaft.
SST 09370±50010
HINT:
The SST should be directly underneath the tube.
(b) Using SST, measure the installation angle of the differen-
tial.
SST 09370±50010
HINT:
Measure the installation angle by placing the SST in the posi-
tion, as shown in the illustration.
