A quality repair shop that does truck alignments can straighten a bent axle trailer for far less than a replacement.
I experienced bent axles on mobile homes a few times when in the mobile home transporting business. Simply removed the axle, took it to a truck alignment shop to have it straightened and re-install. Ezy peazy.
