Big problem, My front right wheel sits farther back in the wheel well??

Has anyone here looked at the K member? Maybe the K member has shifted rearward at that side? Look at the mounting bolts and see if they are loose and maybe they can be adjusted forward some. I'm not sure but can caster be adjusted that much on stock suspension?

If there is another stang you have axcess to lift them both up and check to see if you can find any differencres (k frame, U/L A-arms).
