Aluminum Casting Squeak

I have an application where two 356 aluminum alloy castings are in contact with each other in a clamp type mechanism on our product. There is slight movement in the assembly which cannot be eliminated and is inherent in the design. This movement creates a loud "squeak" similar to that of an old rusty bed. I have tried type 3 ano with a teflon dip which helps but only temporarily.

Any suggestions on a coating which would eliminate the "Squeak"? Would you suggest I coat one of the parts or both?

Dry film lubricant on one or both of the parts might help.
