what kind/size of hitch pin did you use, a paperclip? show us pics of that too.

 

BLASPHEMY!

Jk, but seriously, I haven't had that problem yet.

Pin should be a tight fit.
And if it was I dont see how it could cause any wear.

 

mine looks the same.
i have 25k on mine and tow a trailer that is a little more weight than yours.
my 04 ford did it to. the pin size i use is just the right size so the only other thing to do is something i have been putting off.
run a bead of weld on the hitch itself then grind it to fit so it's tighter.
i did it before with my old tundra and the ford and it seemed to help.
other thing i have seen done is a large flat washer welded to both sides of the hole.

pin can be tight but if the hitch is bouncing around or loose it puts stress on the pin and hole then opens wears the hole on the edges.
just my 2 cents worth.

 

Could it be your ball mount? A little bit small or worn? Maybe you need a sleeve?

 

This all points to a poor ball mount -- I'd replace the ball since it is shaved a bit smaller than the mount that goes on top of it.

I have towed a trailer 7000+ lbs behind my Tundra and it doesn't feel it at all and I use the pin that comes with the stock Tundra hitch and it fits tight!

Sanosuke!

 

Saw this same problem on a travel trailer forum. Consensus there was that the pins with the curved ends caused the rounding of the hitch holes, many posters eliminated future wear with straight pins. I have always used a straight locking pin and have never had a problem.

 

ifd22, you are probably right. I just checked back from the receiver end. The inside wall is not altered, just the outside wall. So it makes sense that the curved pin had made the damage. I thought the steel of my receiver was coming from a bad batch. The only thing I don't like now: the bearing surface is reduced ( the 5/8 pin is in contact with the inside wall only). But ultimately, in worst case scenario, the inside wall would deform to look alike the outside, and the bearing surface would be larger. However, backlash will be present.

 

I too would agree it is probably the curved hitch pin doing the outside damage and rounding out the hole. I can't believe the surface rust on your 07' tundra's receiver hitch. Mine has a few dinky spots, but yours looks like it has been thru a war for only around 2 years of use. Did anyone read on another forum the 2000-2001 tundra's frame and leaf springs rusting thru and breaking just like the 1995-2000 Tacoma's. It seems like the 2000 and 2001 tundras are going to have to be bought back like the older Tacoma's since some also do not meet inspection and are unable to drive for safety reasons. Let's hope we are all not in that same boat 7-8 years from now. Sorry to get off topic.

 

I have the same looking receiver! I too have about a 7,000# TT and it is doing the same thing!

 

same for me also, changed from the curved pin bcause of it.

Also my hitch has the same rust, i will say i am not impressed with that since my truck doesnt go too far in the winter.

 

Mine did/does the same thing with a curved pin. Guess I'll look for a different style pin.

 

It's not the pin that's the problem with mine, it's the sloppy receiver. A normal receiver is made with a nice slip fit for a 2" square ball mount, but mine would take a 2-1/8 square easily and probably would take a 2-3/16. Since the pin fits tighter than the ball mount, the pin takes the twisting load from the load leveling bars when I go around a corner. A right turn makes the hitch try to rotate counterclockwise in the receiver and a left turn makes it try to rotate clockwise. This twisting has ovalized the pin hole pretty dramatically.

It's a sturdy receiver, but the square hole is just too big.

 

Just curious if you guys with this problem are using weight distribution? With my weight distribution there is no stress on the pin. I've arrived at a campground 100 miles away and can spin the pin in the receiver.

 

I have the same problem and only tow a small boat trailer 2,000 lbs. at the most.

 

So, after reading this thread a couple weeks ago, I checked mine.
Same thing going on, wallering out the outside hole on the bent side of the hockey stick pin.

Today I found another locking straight pin option for anyone interested.
Fits our big receivers nicely.

Thanks for the info....just ordered one. Do you happen to know the weight rating of the Class V hitch and pin??

I left the package at home so I don't have their exact #, but I do remember the pin is rated at over 30,000 pounds...plenty strong enough for anything I'll ever pull with my Tundra.

If I remember right, the package says it was tested at 34,000 pounds. I'll check it when I get home tonight.

 

OK, home now.
Package says "Exceeds Test Specifications 32,000 lbs"
Good enough for me.

 

32,000 pounds....darn, I was hoping it would be at least 40k. Mine is on the UPS truck., delivery on Monday.

The hole in my hitch is only slightly deformed from my curved hitch pin. I really don't see where it would cause a safety problem, but I ordered the straight pin to prevent further wear on the hole.

Just curious...has anyone ever had a hitch pin break while towing??? That would be exciting!

 

Right on about the sloppy reciever. I take my hitch out when ever I am free wheeling because the thing rattles inside the reciever, it make alot of noise. This is the 1st for all the trucks I have owned. I wonder if its some type of metric dimension for the reciever.

 

Just got my new pin today, perfect fit. Thanks for the info.

 

well add me to the list. I was using a curved locking pin but today I found a straight locking pin locally.

Most of the straight locking pins were too short for our class v receiver but I found one today. Most of my towing has been under 2500 lbs but I still had the damage as shown in the first post. I would encourage all those who are using curved locking pins to replace them as soon as possible.

I was thinking of just getting a washer and epoxying it to the pin where it curves as I don't have a welder
