(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.

by hand.
SST 09922±10010
HINT:
Use 2 of the same type of SST.
(b) Place matchmarks on the transmission companion flange
and flexible coupling.
(c) Remove the 3 bolts installed from the transmission side.
NOTICE:
The bolts installed from the propeller shaft side should not
be removed.
(d) Place matchmarks on the differential companion flange
and flexible coupling.
(e) Remove the 3 bolts installed from the differential side.
NOTICE:
The bolts installed from the propeller shaft side should not
be removed.
