Rusty ball

I Bought this ball hitch less than three months ago and it’s only sparingly used. But I wonder why this got Rusty here pretty quick. It’s even rated 30,000 pounds


Anyone experience this?

Is it still safe to use?

Heat treated is not hardened. Heat treated is stress relieved so it don't fracture under stress.

If the ball was hardened (and that would only be case hardened not through hardened), it would stress crack. Hardened steel is also brittle. The ball is normalized, not hardened.

I use Vaseline instead of grease, provides the same lubrication and anti-corrosion protection but if it gets on the clothes it's no big deal.

Sure you don't mean forged, not hardened?

That seems counter productive to me. The coupler has to move on the ball when the trailer is turning so a dry ball imparts undue friction. Keep your balls greased, they slide easier.

I don't make it a habit of rubbing my pant leg against my balls so greasy pants legs not an issue and I wear gloves when handling the ball hitch too.

I always tow with grease on the tow ball and the WD pivot points. I am careful when I get around the grease, and don't wear good clothes while working the trailer.

as said above, hardened steel will get a light coating, not pit.

Curt 30,000 balls


A hardened RAW STEEL will rust very quickly (less than a day) unless covered in grease. I think they sell a chrome plated version for more $.
Please give me enough troubles, uncertainty, problems, obstacles and STRESS so that I do not become arrogant, proud, and smug in my own abilities, and enough blessings and good times that I realize that someone else is in charge of my life.
