My bet is inadequate stress relief after welding. Probably didn't take the time to use a rosebud tip.

No, it's not a good weld. It cracked in the HAZ (heat affected zone) which means the weld was not planned and executed properly.

Minor Cracked trailer ball hitch - BAD?

My guess is the weak spot was caused when the bar stock was bent into a "U".

My guess is that it was bent cold, or too cold.

The metal toward the outside of the radius was stretched and weakened.

It is my bet that a rosebud is not used on any production built hitches.

Maybe you should write Equalizer a new weld procedure.

I would send the hitch back to Equalizer for a total metallurgical autopsy. I assume the weld was made robotically. If that's true and the weld process was poorly designed then there may be more than one cracked head out there.
But that's a very broad assumption without forensic analysis. It could be nothing more than simple metal fatigue, overloading, or a defect in the base metal.

My guess is it was welded up by a disgruntled employee with an axe to grind against management.

My opinion is that when the piece that now has the crack was bent into the " U " shape the outside of the bend was left in a stretched stress condition. Then when it was welded and the weld cooled the metal was stretched almost to the point of cracking. There should have been some stress reliving treatment such as heat treating when this part was made but maybe that step got missed this time. Maybe everybody went to lunch as the weld cooled and then ran the part through the stress relieving procedure later? Probably a manufacturing defect when it was made and a good metallurgy lab could tell what went wrong. If it was mine and I had to pay the freight to get it replaced I would weld it properly and expect to never have a problem with it again. There is still a lot of weld holding it together and since I don't usually go much over 55 when towing I would drive it to where the problem could be resolved. I would keep an eye on it to make sure the cracks aren't getting bigger. If there is so much force on that type of hitch set up that you could rip the rest of those welds apart I'd be looking at a fifth wheel type of trailer.

Update on bad hitch

1) yes, its bad
2) Austen Deal a customer service rep at Equali-z-er has been fabulous to work with
3) we went over the image you all saw and then confirmed it was a warranty covered defect
4) I filled out extensive trailer and TV specs in order to qualify the warranty replacement
5) warranty replaced hitch was overnighted - at no cost to me ( i did pay for expedited shipping since we're more or less stuck w/o it )
6) we drove minimally (side streets ; 30mph) as we had to vacate the lot we were parked in
7) there was an extensive walkthrough over the phone with the hitch with Austen .. discussing the washers that were loose and should be tightened, the proper grease spots in addition to on the ball itself;
8) today, we were set to receive the overnight delivery - and it failed to show -- slightly annoying bc we paid the $140 overnight cost and it wasnt sent from shipper in time ... so whatever ... its a 800$ unit so in that sense it's cost of doing business I suppose
9) will be putting on the new hitch upon receipt and have a much better sense of the set up and what to be checking on an on going basis

So that's the update. It was really helpful to read all the comments, even though it was obvious to the knowledgeable outsider, when you're in the TV (Toyota Tundra, 2011, SR5, v8) and you feel all sorts of control ... you just never know.

Thanks for the report. I'll be giving my equalizer the evil eye this weekend.

Ball was loose too?

All in all just a minor detour I hope! How about a photo of your replacement part and your complete hitch set-up? Is the new part exactly like the old one?
