You can do this by measuring from the center of the hitch coupler socket to the center of the front axle spindles on each side.

The measurement must be within 1/4 inch. This isn't an easy measurement to make, and accuracy is important. I wouldn't use a string, too much stretch. Use a metal tape measure, and make sure that both sides are at equal temperature and equally loaded. If one side is in full sun and the other side is shaded, the measurement will be incorrect.

Once you have the measurements for the front axle, measure between the spindles from the front to the second and third axle. These should be within 1/8" between the two sides.

This is a measurement you can do at home. If the measurements aren't equal, then the axles are not perpendicular to the centerline.

If these measurements are within spec, then you should take it to an axle shop and have the axles checked.
Markdoane,

I hope to measure it this weekend, thanks for the information. I will let you know how it measures, JB

For the middle tire to show wear it has to have a problem. Try the light buld trick to check for toe in. Place the bulb along the center line of the tire. The bulb should contact all three tires both front and rear sides of the tire. Cot a piece of 1 x 2 wood or any other straight material to fit just touching the tire rim and place a level upright on this straight edge. The tires will not show level but you can compair them. It is the center one that most likely will differ from the other 2.

Cupping is a balance problem and not your problem at this point. Your's is an alinement problem.

Thanks John,

Is there a feathered edge to the individual treads on the tires that are worn?
If so you have a toe in (out) issue.

If not you have a camber issue.

It looks to me as a camber issue with out the feathered edge for the curb front and center. Also any wear issues with the tires on the street side?

Action,

No, no feathering just outter wear on center & front curb side. Street side seems to be fine. Thanks for your thought, I'll check for a trucking/trailer allignment specialist in the Dallas area.

Based on that data the camber angle is not correct for the application and needs to be adjusted to the curb side middle and front axles. ~ If that is even possible with out damage to the torsion spring inside of the axle.
