Rotating tyres won't do anything other than make sure they all wear out as quickly as each other.
Has your steering rack come loose?
He says he's got new sway bar links, it won't be those even if they were worn out, they just make a little clonking noise constantly.
Jack a front wheel and see if you can wobble it around, if so look and see where it's loose. I agree that you need to explain where on the tyre it's wearing, too.
Another thing that's possible is if you've somehow got too little caster. It would feel very light in the steering, wander like it's on holidays.
But getting it up on jacks and looking at things is going to be your first objective.
