Maybe what you are hearing is the friction between the aluminum wedge thingy and the shell as it "expands". Obviously that can't be greased. Maybe some carbon assembly paste is in order here.

I'll go ahead and say this with my flame suit on. I'm a mechanic that only uses torque wrenches on "Pattern" and/or pressurized and gasketed applications. Like on an engine head, to make sure everything is equal. When it comes to a single bolt application I ignore the recommended specs and just trust my hands. I broke and stripped enough fasteners as a kid to learn how to feel tension change and the warning signs of nearing a limit. Torque wrenches do the opposite. They desensitize your hands and teach you to become dependent upon them. If you use the right tool, and the right size tool, you can just ignore those "Warranty liability numbers" and pay attention to what fastener is telling you.

IMO you should be able to keep tightening the bolt until the saddle won't move. If the bolt breaks or the female component strips before the saddle is immobilized, then there is a design flaw (inadequate sized hardware).
