Yeah they all got like that from hauling coils mostly. We used to flip them over and heat the lower flange of the beam with a rosebud. Put the arch right back in them. I always used a #20. The faster you get it hot, the better it works. When you heat a spot quickly it tries to expand, but the cold metal around it won't let it. So it distorts into a slightly thicker section. When it cools it contracts the only way it can by creating tension in the lower flange of the beam. Do it in enough spots and it pulls a positive camber right back in 2 Quote Link to comment https://www.bigmacktrucks.com/topic/74916-old-school-steel-hauler/#findComment-565078 Share on other sites More sharing options...
