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.

REMOVAL
1. REMOVE EXHAUST PIPE ASSEMBLY
(a) Disconnect the heated oxygen sensor.
(b) Remove the 2 bolts and front floor center brace.
(c) Disconnect the exhaust pipe assembly from the O±rings.
(d) 2JZ±GE Engine:
Remove the 3 bolts, nuts and 2 gaskets from the exhaust
manifold.
(e) 1UZ±FE Engine:
Remove the 4 bolts, nuts and 2 gaskets from the exhaust
manifold.
(f) Remove the exhaust pipe assembly.
2. REMOVE 2 HEAT INSULATORS
(a) Remove the 6 bolts and heat insulator.
(b) Remove the 4 bolts and heat insulator.
3. REMOVE PROPELLER SHAFT
(a) Using SST, loosen the adjusting nut until it can be turned
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.

(f) Separate the flexible couplings from the transmission and
differential.
HINT:
If the flexible coupling cannot be easily separated by hand, in-
sert a screwdriver into the bolt hole of the flexible coupling as
shown in the illustration, then pry the coupling out.
NOTICE:
Do not bring the screwdriver blade in direct contact with
the flexible coupling's rubber portion.
(g) Remove the 2 center support bearing set bolts and ad-
justing washers.
HINT:
Some vehicles are not equipped with an adjusting washer.
NOTICE:
When removing the set bolts, support the center support
bearing by hand so that the transmission and intermediate
shaft, and propeller shaft and differential, remain in a
straight line.
Maximum joint angle: 5°
(h) Push the rear propeller shaft straight forward to compress
the propeller shaft and pull out the propeller shaft from the
centering pin of the differential.
NOTICE:
Press the propeller shaft straight ahead to keep the trans-
mission and intermediate shaft aligned straight.
(i) Pull the propeller shaft out toward the vehicle's rear.
NOTICE:
The intermediate shaft and propeller shaft should not be
separated.
