To answer a few questions:
Do you have the Trailair axle equalizer system on your suspension? If so, which system is it?
I don’t have the Trailair axle equalizer.
Did you back into your present location and made a sharp turn while doing so?
It doesn’t matter if I back it in or pull it in the conditions still exists.
If one side or tire is sitting on a bump or some other surface irregularity, it may have a different spacing than the other side. This is because the equalizer rotates and changes the effective distance between the wheels. It needs to be on a flat and level surface to compare.
It dosen’t matter if it’s on un-even surfaces or not the conditions still exists.
I'm curious why you'd consider making adjustments if you aren't experiencing any abnormal tire wear?
Because I'm heading out on another 2000 mile trip in July and don’t want any problems.
