How do I determine if a torsion axle is shot? I converted a 1969 Apache Mesa popup camper to haul soap box derby cars, and am getting quite a bit of bounce. With a person jumping in the trailer there appears to be very little movement in the torsion arm itself. I plan on replacing the original torsion axle with a new dexter axle, that is more appropriately rated for the load I will be hauling. Which brings up another question. How much over the weight of the trailer and the load should I get for an axle. I haven't weighed the trailer yet.
Thanks
