I have a 2016 Ranger Z519 with a dual axle trailer and noticed that the insides of my rear tires wear really fast. Kept rotating tires and checking the bolt on the trailing arm to make sure its tight but this weekend the trailing arm that holds the hub to the axle slipped and the fender came down on the rear tire and damn near melted it. Looks like the teeth in the trailing arm clamp as well as the teeth on the post that it clamps to are worn or bent slightly. I'm aware I can probably order an axle from the factory and new trailing arms but I'm wondering if there are better options if the trailer is out of warranty. Can't believe a 5 year old trailer would have such a catastrophic episode without some kind of accident involved or something.
