It was the same on both sides, both on the inside. I drove 3k, maybe 4k miles last year, which doesn't seem like all that much.
The trailer is not overloaded - it's 2000lb torflex axle, and CatScale showed axle weight at around 1200lb (I probably added 100, maybe 200lb more - 2 foam mattresses, some food, blankets, couple of things in the kitchen). Certainly not even close to 2000lb limit.
The wheels have been angling outwards from the beginning (toe-out). I was told this would resolve with some towing as the rubber in the axle settles in place, but that doesn't seem to be the case.
Any ideas of what to do? From what I know torsion axles can't be aligned in any way...
