Mine creak too. I usally hook mine up and tighten them after I pull out of my drive, and disconnect them when I pull into the campground. I have a convienent place to stop to disconnect right out of my drive. When travelling, I try to not do any tight turns in parking lots where I stop. Right turns onto another road is as tight as I turn with them connected.
Some are adjustable, try to find out if yours are. I'm guessing some noise is normal as friction will cause noise.
