Tractor Repair: fornt end loader not level, ford tractor, mesurements

Question
I have a front end loader on my 1996 4835 Ford tractor. one side of the loader is about 3" lower than the other(not level) It appears that it may be sprung or somehow the mount shifted. How can I determine what is causing this and is there any way to fix?

Answer
its hard to say without seeing it
are all the wheels the correct size
the frame could be twisted if you mesure the distance from the front pin on the right hand side and the main boom pin on the left then do the opposite front left and main right and compare the mesurements they shoul be the same or very close
