Shakey, since the pinion nut is a castle nut, your special tool should work well with the impact wrench to get the nut to back right out without any damage to the nut. Just be sure to apply pressure onto the nut so that the special tool stays fitted well when the impact wrench starts doing its thing. I do recall using my impact wrench to back out the pinion nut last year. Worked real well.
