Repairing a trailer hitch

One of the holes in the car hitch that the pin goes thru to hold the shank and ball in place has elongated, possibly from using a small diameter pin.
Any Ideas on how to repair it?
Thanks

I have no idea why only one side is being elongated. Hitch pins are a standard size. You could clean it up and run a weld bead around it then redrill the hole. I weld but am not a welder and have always heard that a good weld is stronger than the metal but.........might just be better off in the long run to just replace the hitch. How are the holes in the stinger, still round? Metal fatigue comes into play at some point also. In all reality it may not be a safety problem at all. If you think about it all our hitches get worn as we use them. When new the pin was tricky to get through, years later it goes in real easy from use.

Dave has some good thoughts. Might want to have a good hitch shop have a look at it too.

Could the holes be drilled out and an oversize pin be used ?

One could have a heavy washer of the correct size welded on either side.
I have no idea why one side wallowed out and the other did not.
If a new hitch were not too expensive it might be as cheap to replace it as getting a good welder to repair the old one.
It all depends on the cost of the welding and how good they are.
If it wallowed out and the proper hitch pin were used it might bring into question the quality of the original hitch.

Drill the hole oversize, have a bushing made which is simple lathe job, weld it in. Wouldn't matter if it stuck out a little

There is no reason to have to replace the hitch. Either Dave's or Mary and Bob's fix should work just fine. I would probably just weld and re drill the trick will cleaning up the inside of the tubing so the stinger still fits. I would think a Dremel Tool with a grinding wheel should fit in side and do the job.

I agree having a reputable hitch shop look at it would be a good idea.

Cause of it would be of concern to me. I know I in the past owned a new to me vehicle that this had happened prior to my having purchased it.

Local hitch shop suggest that the most common cause of it is the trailer it had pulled either had no brakes or the brakes were set incorrectly resulting in excessive push and pull on the hitch. A poorly fitted hitch pin would have added to the problem.

When one metal is softer than the other - the pin is probably hardened, the receiver not, wear will occur. If both metals are the same hardness, they will polish each other. A loose pin could cause adverse wear. How old is the hitch?
What size is it? Class I, Class II, Class III? How much does the shank and ball wiggle in the socket? After you make repairs .... I like the idea of drilling to an oversize pin ... Try to take up any looseness with shims, or a snubber kit. Your Hitch Shop should be able to help there.

Welding in and redrilling the hole would be OK using the right rod, but it would be hard to get the new hole perfectly centered, the weld may push the drill bit off center. If the hole is resized or repaired, then use an "anti rattler" or tightener device. One of my hitches I have to use a shim on the side too

I am guessing that the stinger has over size hole in it. The pin should be forced square through the 2 inches of the stinger. If one side of the receiver has wear the stinger has to allow it. The stinger has to be loose in the receiver to allow this to happen or the holes were out of square and are now self correcting. Take it to a hitch specialist. a good shop has all the equipment to fix this.

Elongated Hitch hole

Thanks to everyone for the suggestions. I have been thinking of taking it to a weld shop and having a 1/4 inch rectangular plate welded to the hitch over the hole and then inserting the shank and drilling through from the other side.

How much a weld shop will charge you just to look at your hitch? Compare with the price of the new hitch ($150-200).
