I have a Ziess that had really noisy linkage and brought it to Wayne Tenabe at the Brass Bow outside of Chicago. They put on new linkage rods and tapped a screw into the brass portion that goes over the rotor. The linkage is really quiet now. The only downside is to take the rotors out, I need to unscrew some allen screws. I have never seen anything like this done but it works great.
