Look for some type of over travel of axle. Made lot of hoses, pulling apart at the crimp is not a normal failure from pressure. more of stress from alingment, twist or pull

Do you have a 2 1/2 inch receiver? 2 inch pin.

Bypass the air dryer and see if it works,I had a relay valve on a cement mixer, cause low air on a tag axle.good luck

Does it have a steering stabilizer?

bad sensor?
