I'm with Mr. Smith.Clearly not enough toe on right side
________I thought the rear was not adjustable? It's sold axle. On the front the little #'s are the specs, so each one is within that spec. You tried swapping the front tires? See if the pull moves with the change. Might be tire related.
_________i am takeing a auto tech class, when you align a explorer you have to put the rear sencers on for a referance for the the angle of the front tires. even though it isnt ajustable it still tells you what the angle is. that is why the specs are grey insted of green.
I bet if you hit a tall enough curb going fast enough the axel could slide on the leaf springs, so you would have to slide it back to align it.
