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.

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:
