Everyone should check the label on your hitch.

My Hummer H2, bought new, is rated to tow 8500 lb on the brochure, but the OEM class III hitch equipped with the truck had a label on the receiver indicating the capacity of 5000 lb.

??? confusing, huh?

I looked at under the chassis, and the hitch only hangs to the ladder frame of the vehicle by c-channel like clamps that are inch or less depth. It did not seem strong or confidence inspiring to tow my beloved trailer. Imagine it is as if a rock-climber is hanging on the cliff wall only with fingers.

Well, I took the truck to HitchMasters of VanNuys (great guys!) and they reinforced the hitch by welding a few more square beams and gussets. And re-rated it. The hitch itself is now labeled for up-to-12000 lb.

Thanks guys some great input!

I can't post more pics untill tomorrow, I don't know the rating offhand but I believe it should be 12000 and it is suposedly the factory heavy duty package.

Vajeep has a great point... Yes it is a 'bend' pin I will start looking for a straight pin... Any online resources for that?

Luckily I bought this truck from a dealer and he told me he'll replace the hitch for me. And also the hitch receiver was allready installed, the airstream dealer did put on the equilizer hitch part.

The other side of the hole is not damaged I will post more pics tomorrow

Interesting. I do wonder if GM had a bad batch of hitches at one time or the other. I've been checking the hitch on my 2003 3500 dually on a regular basis and I've yet to see any signs of unusual wear or weakness.

The answer to your question is YES . GM had some bad hitches. The welds went bad or were not welded properly . I am not sure who the mfgr was. Gm Did do a recall of those hitches. Hopefully someone will chime in with the yrs. I know it was posted here on the Forums,there was a red flag here to check all GM hitches of a certain yr. I'll be dinged if I can remember what those yrs were.

The way the hole is elongated only at the 3 o'clock point (and not the 1 or 5 o'clock)on the back side makes me wonder if the hitch pin is too small diameter? And... if the wear is at the front of the receiver hole - does that suggest there is excessive trailer push forward for this type of wear? I would expect pulling wear to be at the rear of the pin hole.

Looking at the photos remind me of when I was not retired and working with a couple of iron works folks. One individual manufactured suspension systems for off road and large trucks and the other person used sheet steel for art work. Seems as though when the majority of the steel was manufatured in the U.S thequality of steel could be depended upon. When it was shipped overseas the quality of steel was pretty iffy. Sometimes you would get fairly decent steel and sometimes you would get soft steel. This could be the problem here and GM picked up some receivers tht were made from a softer steel.

Just a thought.

Every now and then I get one right I read all the horror stories about the "bad OEM" hitches and it turned out that my problem was only the bent hitch pin. Like your receiver, I only had damage on one side, and when I switched to the straight pin no more worries.
Our Overlander is about #6080 fully loaded.
You should be able to find a straight hitch pin with out too much trouble. I went to a Tractor Supply store in Virginia we have lots to choose from. I would like to ge the pin in person to make sure that the new hitch pin was an "exact fit".
Good luck!!

Every hitch receiver I've used with the J-type pin has elongated the hole as shown.

Since I hate to throw serviceable things away, I am still using this type pin, but I install a large washer on the side of the pin with the bend in the "J", which prevents the bend from wallowing-out the hole. To keep the washer on, I use a hose clamp. No more elongated holes.

I seem to have a similar problem with a Ford receiver. I do use a "bent" pin and I used to think that it was because maybe it was a bit too small in diameter however I took a good look at it today and I'm not sure that it doesn't have something to do with the Equalizer not being closer to the same size as the receiver. There seems to be too much slop between the two. Maybe I don't have enough to complain about because mine has more years and more miles on it. I don't know what to expect. I did notice an advertisement for Draw Tite for their J-Pin that has a big nut on one side that tightens it up against the receiver to cut down on play.

Any comments? Or ideas?

BTW: It says the max trailer weight is 8850 lbs

I had problems with my GM receiver having too much play. My solution was to replace the square reciever in the hitch with one I bought at a trailer store that was made from thicker material. Took the whole thing off and to a welder, had him use a plasma cutter to take out the original, and then I welded the heavier duty receiver in place. At that time I put more weld on it making sure I got good penetration. Haven't had any problems since, and the whole deal was less than $40, but a little work.

Replace the reciever...

IMHO

For the $'s involved it's worth the piece of mind. I still work PT at a GM store, we have replaced more than a few under warranty for weld cracks. (replaced with OEM, whats the point?) My rule of thumb, if it has the round cross bar replace, if square bar, inspect often for signs of weld cracks. Both styles have been suspect.

The factory receiver on our 06 3/4 Burb did not inspire confidence, it was changed before our first trip.
