CAUTION:
When servicing the propeller shaft, support both ends of the propeller shaft evenly to limit the movement of propeller shaft joints to a maximum of 10 degrees. Do not let the propeller shaft hang unsupported at any time, as it will cause damage to the propeller shaft boots

NOTE:
Due to the weight and length of the propeller shaft, not allowing excessive movement of the joints may be difficult during removal and installation. It is recommended to use the aid of an assistant to remove and install the propeller shaft.
