I had that happen on my boat trailer when I was up in Canada on a fishing trip, the axle bent 180..
I had the trailer towed with a dolly under the axle.. as I was cutting and grinding... I had my brother
drive 75 miles to the next town to see if he could find a spring.. we got lucky and he did.. when he got
back I was ready for the spring... the shop rented me their welder and torch.. they charged me big time
for 20 minutes for me to weld it up... we were down for about 3 1/2 hours total
