How to correct positive camber

I've got a 2007 Karavan single axle trailer, a 2008 Alumacraft Navigator 165CS boat, and a 2009 Suzuki DF90A. I bought it all brand new in 2009 and have to replace the tires constantly. My cabin is a 500 mile roundtrip, so definitely a haul. However, you can see the positive camber in my wheels. They wear exclusively on the outside edge. I usually then have the tires flipped on the rims until the other side wears out and then buy a new set.

I haven't weighed the setup, but by my calculations it weighs about 1,800lbs. The GVWR on the trailer is 2,690 and the Max Load Carrying capacity on the sticker is 2,200lbs. My theory is that they gave me a trailer meant for a heavier boat, therefore the camber doesn't flatten out because there is not enough weight on the trailer.

I thought about removing the smallest leaf from the suspension, but think that might introduce too many other problems such as bottoming out on bumps, etc. I read about cold bending the axle as an option. There is a specialty alignment shop nearby that says that he can do it, but I wanted to see if others have gone this route.

The 400# difference is not enough to cause this.

Need photos of:

Axle, from the front or rear. Is it curved, either up or down on the outside edges?

Tires on trailer, view from the front, looking at the tread. Is this camber clearly visible?

Also photo of the spindle sticking straight out, with a steel square, to show if the spindle is parallel to the ground.

Maybe the axle was mounted upside down ????

Have you contacted Karavan about this issue. They are a helpful bunch.

FWIW, my father's trailer had a weird tire wear issue and the trailer would not track straight. This started when the trailer was 4 years old. The tire wear was down the center, but each tread block was worn unevenly. Karavan immediately knew it was a bent spindle. No one knows exactly how it got bent, but we are sure dad smacked something real hard on some Canadian logging road.

That looks to be also toe in or out as well , for that to be camber alone the wheels must be damn near dragging the hub caps too. Pictures of the whole set up would be great ....whatever it is has got to be obvious .🙂

Usually trailer axle alignment is adjusted with heat and a brake press by physically bending the axle
