My axle became bent on my Skeeter ZX190 and I discovered this is common on single axle trailers because of weight, hitting bumps and rough roads. I took mine to a shop in Lewisville and they installed a new heavier axle for less than $200 and mine has disc brakes. These axles take a beating bouncing up and down the road. If you watch your trailer tires as you drive on some of these rough roads you can see the tires flexing. I understand Phoenix has shocks on some of their trailers. Wish mine did.
Everything is funny, as long as it's happening to somebody else.
