Measuring axle possible bent any suggestions
 

kind of stuck I am trying to find out if one of the axles on my trailer is bent? Its a tri-axle phoenix. Any suggestions on how to go about checking to see if it is bent. It seems to track straight while being towed. I am going to do a 900 mile trip just dont want any issues.
Thanks

I had to do that once. All I can say is make an overhead sketch of your trailer and axles, and get a good tape measure and a good helper. Start taking any measurement you can think will help. Such as left wheel to right wheel, front and back. diagonal from left to right front axle to axle. From axle to ball coupler on both sides. ETC. Jot down the measurements on your sketch, and it will start to make sense to you. But first, make sure you've rolled your trailer in a straight line to let the axles settle before starting any measurements, as the axles twist a little during turns.

Are they straight axles on leaf springs, or torsion axles?

Thanks for the responses. I actually got in touch with the manufacturer. They gave me the info I was looking for. With that all said the axles are not bent, its the way they are built.
Thanks anyway
