Notice: 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.
Important: Do not drop the bearing cap assemblies of the yoke end.
