I run mine dry more of it ends up on me than the hitch. I can be ten foot away and it still get it on me. Whats every one else do wet hitch or dry hitch.

Dry!

I have never put grease on any of my hitch balls... I tow a 14,000lb equpment trailer on a ball all the time, no squeeking or metal shavings. I also use a pintle on my 20,000lb trailer, now that one makes some metal shavings..

I keep grease on the 2 5/16" ball, none on the smaller ones. Just the way I was taught, don't know if it makes a difference.

never greese my balls ?

Why do they grease 5th wheels?

Mine is greased, won't hurt to do it, get a trailer ball cover to slide over when you're around it. My hitch is removed when back home anyway.

Does white lithium grease work? I think it would be less messy.

I spray a little clear silicone on mine about once a month during season. That's it.

If I don't put grease on my 10K rig, big metal shavings and yes always gets on me and the kids. I keep a roll of paper towels in the truck as soon as unhitched the ball gets wiped off.

I never grease the ball and never have any shavings. I use a solid ball and have no problems. The only thing is that if you don't use it, in about a month you will get a little surface rust on it. That comes right off when you tow the next trailer
