Hitches can make alot of noise. The noise doesn't neccessarily mean bad. Slow turns can make it screech and whine..it's not hurting anything. It's just some folks don't like the noise. My father always toldme, if it's groaning and whining...it's working. There are some manufacturers that don't recommend greasing the friction points. Greased friction points can eliminate some of the sway properties of particular hitches.
