Equalizer Hitch Noisy

I can tell there are a bunch of smart folks on this forum, so pardon me for asking some "newby" questions. I have noticed that the few times I am pulling my T28RK Cat that the equalizer hitch I've got makes a ton of squeaky grinding noises as I turn, go through dips, etc.. I have placed some grease on the bars where it is attached to the tongue of the trailer, and have kept the area greased where the bars go in the stinger. That has helped a bit.

Do any of you have additional suggestions that would help in squelching this noise?

Thanks so much for your input!

I think most of the squeaky noises are because the of the tentision that is put on the equalizer bars.

It's just the nature of the beast brady,I think you can grease and oil those things till the cows come home.Mine did the same thing. If you listen close,you'll notice everyone else's probly does too.It doesn't hurt anything just annoying.
