For this week's issue of "The Ozark Trailer Sales Service department", we want to raise awareness of the heartache that can be caused by cargo trailers with inferior frame material. We had a customer bring in a 7x14 tandem axle cargo with a pretty well known brand name on it. The customer stated that his tires were rubbing the fender. So our first thought was that the torsion arm on the axle rolled; which is rare, but not unheard of. We pulled the tires and inspected the axles; all torsion arms were exactly where they were supposed to be. While we were inspecting the axle, we noticed some pretty concerning cracks in the mainframe. We told the customer we would have to pull the floor up, grind out the cracks and re-weld the affected areas fish platting when necessary.
