Let's see, if you put the rear axles in the front hub, they would be too long and the axle would move back and forth (lots of slop). If you put the front axle in the rear hub it would be too short and you would not be able to install the hex.
It looks like to me that he needs to set the correct droop, start with about 6 in the front and 5 in the rear. Also the problem could come from the camber links in front being too long, pushing out the front C Blocks, thus making one or both dog bones extend outward. Check to see that both front camber links are equal in measurment. Make sure they are installed in the same position left and right.
I hope this helps.
