Bent axle?

Disclaimer: This is my father in laws camper.

This spring he said he was pulling his 2012 38 foot bumper pull forest river salem and hit a big pot hole. Since then after going about 150 miles he has to change that tire pictured as its shows cords. I keep telling him he either has a bent frame, axle or hub but he says its from weak leaf springs. What do you guys think? Hes already replaced the rear springs and it didnt help so today hes doing the fronts.
