All those pics really show the results of weight
and torsion on the axles.
You can really see the positive camber on the axle tubes and the negative camber on the spindles. Unless this is an abberation from the camera and/or lens, I'm thinking it's time for a new axle.
I'm wondering if this is the problem the Scamp
groups are experiencing with tire wear?
Is there a sticker or name anywhere on the axle that might give a clue as to the manufacturer?
If not, somebody at Dexter might be able to tell from the pictures of the mounting brackets.
Current model Dexters have an attachment at both sides of the bracket to the tube on their current models. Look at the high profile bracket diagrams here:
They don't look the same as yours.
