For those of you who have the "Equil-i-zer" brand sway control hitch, follow this link to their website and download the Owner's Manual.

In the 6K-14K Owner's Manual
Page 23 it states:
Quote:
The friction surfaces of the head and sockets should be kept clean and
well lubricated with a good quality multi‑purpose or bearing grease. These
are the surfaces where the arm sockets rub against the top and bottom plates
of the head. See Figure 23. We recommend Equal-i-zer high performance
lubricant.

Page 26 states:
Quote:
Noise is a normal occurance when towing a trailer and using any weight
distribution or sway control hitch.
The majority of hitch noise can be eliminated by lubricating the friction
surfaces of the head as shown in Figure 23.
In some cases the friction on the L-brackets can generate noise. Lubricating
this joint is not recommended. A better solution is a set of official Equali-
zer brand Sway Bracket Jackets™. They quiet the ride and reduce wear
without the mess of using a lubricant.

This website information helped me to understand a) where the noise is coming from, b) why it was happening, and c) how to eliminate a majority of it. Hope this information helps.
