Wavy inside tire wear. Bad alignment?

Well I broke it free easy from the front. Going back this morning to get the nut replaced.

Once we break it free, can we just remove the nut off the back, without taking the whole bolt out?

 

Well, this keeps getting better. After showing them how to loosen it, they flattened the damn tabs out and couldn't get the tire back in spec.

Thinking about bending them back and running a bead down the back. Is this necessary? I found another guy that's been doing alignments for 30 years who thinks he can get it back with a come along and pry bar.

FML! This is what a simple alignment turned into! I guess in the future I'll have to do my own damn alignments too.
