Mate two flexable two assemblies.

I have two Flexible sub-assemblies that hold a shaft. I mate one to the shaft, when I try to mate the other to the shaft it tells me the mate will not work because parts are two far apart. I have it in flexible mode and the configuration in flexible mode. I need to see this move all the way through because I need to look for any interference with other parts. I have done it in the past but have had problems with it not moving the way it does in the sub-assembly. Any help? Example attached.
