An interesting observation after my first season towing

It's possible to have a bad weld - but pretty unlikely. These are all welded by a robot with pretty sophisticated electronics that monitor the welds. If you ever get a chance to see one in action - it's pretty amazing. I'm also in the camp of it probably being paint defect, but I'm curious to know. Any chance you could take some better pictures?

Ah I couldn't tell by the picture very well and thought the actual weld was cracked. So this is a whole different issue entirely, my bad.
 
A better pic ain't gonna be much, guys. There is no discernable stress cracking or other visible naked eye flaws, just the missing paint. The location and fact of no other similar paint issues in nearby locations or welds is what flagged it for me. Certainly hope it is just a crummy paint job, but it'll be a little while before I can pull this and investigate further.

So why are you concerned if there is no crack? If you look at other spots on the truck. like front UCAs, shock mounting tabs.. you will see very similar cracking of the paint (or will eventually). This is very normal IMHO. Steel flexes under load...
 
Why not just replace the hitch with a new Toyota part? They can't cost THAT much. If the new one does it return it and get another new one. Much easier and probably cheaper that analyzing the old one. When you use things they wear out, it's the cost of doing business.
 
Looking at the welds it seems they are excellent with good penetration and the bead just below the paint free area shows no flexing.....I believe it's a paint issue. Yes, I am a welder but you should do whatever will give you peace of mind with this!

Because it is worth being cautious based on the fact that this is a high stress zone, paint is missing here and in no other spots on the same component, older models with similar hitches are excluded from using a WDH, and I don't generally carry a mobile welder to field repair a failure nor do I have any interest in watching a 3500# big white fiberglass apartment on wheels fall off the back of my truck. :)

That is the great thing about a community like this though. We can all benefit from one another by way of shared experiences, knowledge, observations, etc from those who've gone before or are around us.

I agree, it is worth discussion. I just don't think it is unusual for paint to chip/flake off steel on a highly leveraged spot. There are plenty of spots on the structure of the truck where this happens and it is normal.

The picture looked like there was an actual crack, which I think confused some folks even though your words said there was not....
 
I see a pinhole in the weld crater and a little bit of splatter. There are nice gussets further back and the top gusset going all the way to the end of the tube would be stronger. Dye test is your best bet. Weld might be undercut or it could just be bad paint prep.

Forget that, go all out and replace it with a GX460 hitch and call it good. Pretty sure it bolts right in.

Interesting. What would be the advantage? I've got to do something about mine.

OP, I would certainly have it inspected by some who knows what they are doing but it's probably bad paint and rust. Here's
mine which is a 2010.

There you go, that right there ^

OP, you are suspicious of that receiver, and in your mind this is not going to go away as long as you have it.

mine started to rust after a couple months

hit it with some POR-15 though and it looks good now, the POR-15 hasn't even scraped off when i've dragged it on rocks

That's my current plan for the fall, clean up this and some spots underneath with the POR-15. Hadn't thought of bolting on a new one or using the GX hitch. Probably stick with the POR 15 as it's more than just the hitch that I want to hit. My towing is just utility trailer around town, heavy when I get mulch or gravel but the trips are only a couple of miles. Mostly the hitch is used for bike rack.
 
pay attention to the holes for the pin if you POR-15, I made it too thick there and had to dremel grind some of it off so i could get the hitch pin through
