Help with tire wear

I have an AF 1140 with a 48 inch Torklift Superhitch/truss system to pull a 7x12 tandem axle cargo trailer. Also use a wd hitch. The trailer sits just slightly nose high when parked on a level surface. Here is the best pic I could find:



I am getting wear on the outside of the tires on the front axle. Passenger side is worse but also happening on driver side. My thought is a bent axle. With the odd(for everybody but people in this forum) setup I am wondering if maybe it is a combination of the heavy TC/long extension/wd hitch. I know I use much of my suspension travel going over bumps on the highway. No bottoming but my guess is the deeper into the suspension the truck goes the more the WD hitch is removing weight from rear axle of truck and front axle of trailer.

Any thoughts on what to do?

  • Think I'd get it aligned and have the toe and caster and camber checked with the camper on the truck.
  • The truck camper puts almost all the weight on the rear axle of the truck. It adds almost insignificant weight on the front axle. Your trailer's weight distribution system will add at most a minimal amount of weight on the front axle of the truck. Some of the redistributed weight is put on the trailer's axles as well. You should look at alignment issues first. Best to take the combination to the scales and determine what the axle weights really are and take it from there.
  • Front axle of the truck or the trailer?

    If the trailer, lower the hitch head so it tows level.

    If the truck, you're way light on the front.
