I have a 98 Stratos Trail trailer and the tires have began to start wearing on the inside edge. I'm suspecting loss of camber in the axle. My question is can Camber be put back in the axle and it hold? I ask because my axle is square tubing with a 4 inch drop and i can't find square tubing drop axles anywhere. Only round ones. I am assuming if I make the switch to a round axle i will have to change my leaf springs too. Axle is 81 inches hub face to hub face.
