f. If using a new propeller shaft (w/phasemarks):
Install the propeller shaft phasemarks and differential/transmission phasemarks so that their
respective alignment phasemarks match.
If the propeller shaft phasemarks and differential/transmission phasemarks do not align, install the
propeller shaft and differential alignment phasemarks as close together as possible.
g.If using a new propeller shaft (w/o phase marks): Install the propeller shaft.

29.FULLY TIGHTEN CENTER SUPPORT BEARING ASSY NO. 1
a. 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 in the illustration with the vehicle
in the unladen condition.

SST 09922-10010
Torque: 69 N.m (700 kgf.cm, 51 ft.lbf)
HINT:
Use a torque wrench with a fulcrum length of 34.5 cm (13.6 in.).
30.INSPECT AND ADJUST NO. 2 AND NO. 3 JOINT ANGLE
a. Stabilize the propeller shaft and differential.

1. Turn the propeller shaft several times by hand to stabilize the center support bearing and
flexible couplings.

HINT:
Measure the installation angle by placing the SST in the position, as shown in the illustration.
3. Calculate the No.2 joint angle.
No.2 joint angle:
A-B = -0°39'± 30'
A: Intermediate shaft installation angle
B: Propeller shaft installation angle
4. Calculate the No.3 joint angle.
No.3 joint angle:

B-C = 1°15'±30'
B: Propeller shaft installation angle
C: Differential installation angle
