Ball Joint Simulation

What would be the best way to create a ball joint between twocomponents in an assembly with 2009 premium? I need to insert aroller shaft into a spherical OD bearing, and have them movetogether but rotate freely. I'm not interested in displacementsanywhere near the joint, so I may be forced to recreate thegeometry and use points with short rigid links? Not sure that willwork, are any other approaches that I can try?
Thanks
