I'd just shim it myself. I've never seen anything so over and under engineered at the same time as two pieces of tubing with 16 bolts.

 

It's a weird way to fix that problem, but I don't see a huge problem with it...unless you start pulling some serious weight.

I wouldn't be surprised to see a good bump in the road deforming or busting a few bolts though...welding on some nuts like mentioned before would probably fix that issue for a while.

 

Decided that when I get around to it that I'm gonna weld a second receiver hitch onto my tow bar and weld a second receiver tube the that hitch carrier. So instead of the whole thing hanging off one attachment point it will have two.

Used it last weekend and it worked ok. Wobbled a little bit but the main problems were that it is not level, the driver's side of the carrier is about 6-8 lower than the passenger side, so when backing up or driving up a steep driveway the carrier will scrape.
Another problem is the carrier is made in China...so it is under engineered and if I tie the straps down too much the whole thing "bannana's".

 

Drill a hole in it, put a shoulder bolt through it with a hole that is just enough to get it through. Should take alot of slop out of it as the pin that holds them is already a bit bigger then the tin..

 

What's a shoulder bolt John? I'm up for any temporary solution right now.

 

You can use one with a hex head. If you drill a hole towards either end with a hole that is just bigger then the bolt, it should take A TON of slop out of it.

 

Cool never seen those. Might have to check it out.

 

Really? never seen them before? All the time you have spent on a ship. Thats kinda nucking futs.
