Equa-li-zer Severe Wear Help!!!!
I have had this hitch setup for the past eight years on a previous trailer, I now have it installed on a new trailer, we have taken six trips with the new trailer without any issues. While pulling the...

Thought to touch on bearing surfaces for a moment before get yet again
slammed for being out of context or not knowing what the heck... :S
ONE of the ways they OP's hitch system manage sway is with
'friction'. This link is from Equa-li-zer's web page
The Engineering Behind the Idea
Their 'friction sway control', #4 & #5 on their webpage, points to
the trunnion bar pivot end. Where it is held onto the shank head with
a through bolt for each trunnion...and the 'L' bracket
What is missing and am finding out that lots of folks do not understand
nor accept that there is another 'sway' control by the bars (either
round or trunnion) and that is that the pivot centers between the
ball and the two bars are offset. So the bar end attachment to the
tongue swing in differing arcs. There is a push/pull that 'resists'
off center alignment of the center line of the trailer and TV
In both cases, it is metal on metal, with no sacrificial friction
material...that I know of, nor see.
This is where others have lam-blasted me in commenting reading that
folks grease/oil these mating surfaces because they make noise by
saying that is an oxymoron...designed in friction and then the user
applies an 'anti-friction' material (grease and/or oil)
The amount of friction would depend on the clamping force, the
RMS of the mating surfaces
On this thread, the OP has discovered gouging and unexpected wear
on the mating surfaces....where those mating surfaces are designed
in...since no sacrificial material, the base material has become the
sacrificial material... :(
Acceleration most likely due to some abrasive materials found it's
way onto/into the mating surfaces
