just my 2c worth, but i don't see how the axle could move over 7/8 of an in. and the center bolt is not broke and still in the hole. if you had the front axle, front end set up satisfactory at one time and 1 mo. down the road you are running dog leg down the road again then something would have had to come loose, broke loose, or bent to make it move that much. looks like to me what ever you had to move back into place to realign it would be where the problem is.
