Grease trailer sleeve coupler

[azuerch]

Hello I have a PJ 12ft utility trailer that has a slide style sleeve coupler. It has become increasing difficult to lock/unlock the coupler and I'm not sure how to grease or oil it. The style is like this:

It only slides maybe and inch or so (by design) and there's no want to disassemble it that I can tell to clean and grease it up good. I can spray something like WD40 under the sleeve but I'd like to use something that will stick and last longer but there isn't much of an gap to spray into and it neesd to penetrate fairly deeply. Any recommendations?

Never seize ... Pull it back, add a little ... A little goes a long way!

WD40 is not a lube. I'd ask/call PJ themselves.

You could try a motorcycle chain lubricant. There's also lithium grease in a spray can.

 

[WM75Guy]

I use spray white lithium grease on my hitches. I also spray the ball every time before hooking up. Less messy than axle grease.

I would probably use Fluid Film spray lube. Smells awful but sticky and works great.

I use graphite spray on my hitch shank and white grease on the ball. While graphite in spray form will rub off, some does remain. I don't know if it would work it's way inside of the slide on your "bulldog" coupler or not?

It is most likely a build up of grit and garbage. Brake clean or WD while exercising it, then a powdered graphite to lube it. And grease or oil is going to attract dirt and dust and gum the works up.

I use this where I need a lubricant that wont attract dust.

I never use anything for last 20+ years. Been towing all my life.
Found that when I used something, it just attracted dirt.

That looks about the same as the T9 in my post above, except in spray form.
Goes on wet and dries in seconds.
If it works on motorcycle chains, it ought to be good for a slide style sleeve coupler on a trailer hitch.

Same. Used some Fluid Film on one once. Thought being it would last longer. Made to messy too work with and attracted dirt until it wore off.

The strongest coupler out there. I never lube mine. The first thing I do when I unhook is take my jack block and tap the sleeve. Loosens right up and then it operates easy.

Thanks for all the suggestions. I did contact PJ trailers via the question form on their website and never heard back. That was many months ago

IMO, I use this for the slide

Dri-Film Lubricant with Syncolon® (PTFE)

Super Lube® Dri-Film Lubricant cleans & carries the dry lubricant powder to the components to be lubricated, rapidly evaporates, leaving behind a Syncolon® shield

and this on the ball

The strongest coupler out there.

If it's an original, yes, but I got a copy (guess the patent expired) on a trailer and it was not good at all.

Fixed it by converting to a tow ring, like I do on most bumper pull trailers that doesn't need a WD hitch.
