NOTE:

When removing the propeller shaft, do not attempt to remove the shaft by 
pounding on the yoke ears or using a tool between the yoke and the 
universal joint. If the propeller shaft is removed by using such means, the 
injection joints may fracture and lead to premature failure of the joint.
