I understand. But let me say again that if the moaning is coming from the hitch and springbar assembly, it is not primarily a lube issue. And lubing it won't cure the moaning, at least in tight turns. Try this, right in your driveway or at the side of the street. Turn your tow vehicle sharply, as you would if you were turning a tight corner or backing into a campsite. Then stop and look at the hitch. You will find that the side of the hitch on the outside of the turn has moved forward relative to the trailer, and the side at the inside of the turn has moved rearward. Since the springbars are attached to the hitch, they move forward and back, too. And this pulls the chains off vertical. When the chains are pulling at an angle, it puts tremendous extra stress on the entire mechanism. And if the chain is too short, it will pull right out to horizontal, and something will break. This will be expensive, and your trip will end on the spot until repairs can be made.
The right solution, and an easy one, is simply to tilt the ballmount backward a little. This will lower the tips of the springbars, allowing you to use another link or two of chain to get the same amount of lift. The ballmount's tilt angle is intended to be easily adjustable.
There are some good thoughts in the middle of this long thread, from about post #8 to #18 or so.
