Caution
•  If the constant velocity joint is bent during propeller shaft removal/installation or transportation after servicing, the constant velocity joint boot may contact the metallic cover and the boot may be damaged. Insert a cloth between the boot and the metallic cover before servicing to protect the boot.

Propeller Shaft Removal Note

1.  Place alignment marks on the front-side companion flange and constant velocity joint, and the rear-side coupling component and rear yoke before removing the nuts.

ac8wzw00002139

Caution
•  Do not use a punch to place the alignment marks. Otherwise, the balance of the propeller shaft may change.

2.  Loosen the nuts (front, rear, and center bearing support).

3.  Remove the front and rear nuts.

Caution
•  The propeller shaft is engaged with the studs.

4.  Contract the propeller shaft and remove it from the rear side.

Caution
•  Do not bend the propeller shaft to the point it contacts the boot.

5.  Remove the center bearing nuts and then remove the propeller shaft.


Propeller Shaft Installation Note

Caution
•  If the nuts are loosened, verify that the stud bolt tightening torque against the coupling is 6.4 N·m {65 kgf·cm, 57 in·lbf} or more. If the tightening torque is within 6.4 N·m {65 kgf·cm, 57 in·lbf}, tighten the stud bolts to a tightening torque between 6.4—9.6 N·m {66—97 kgf·cm, 57—84 in·lbf}.

•  When loosening the nut, if a nut is stuck to a stud bolt, replace the stud bolt with a new one.
•  When replacing the stud bolts, clean off oil and foreign matter on the bolts and coupling installation areas in advance.
Note
•  The stud bolts are entirely threaded and either end of the bolts looks the same.

1.  Clean off any oil on the tightening area.

2.  Align the alignment marks and temporarily tighten the nuts (front, rear, and center bearing support).

ac8wzw00002139

Caution
•  Do not bend the propeller shaft to the point it contacts the boot.

3.  Tighten the bolts on the front side to the specified torque first and then tighten the bolts on the rear side to the specified torque.
