Pita spindle nut!

If you have tool rental nearby, rent a 3/4 electric impact driver to remove nut. When I wanted an air impact gun, guy said you need a big compressor to use it. I needed it for a spindle nut on a 90 honda. I now own a Harbor freight cordless , called earthquake and it doesn't work up a sweat with pinion nuts or crank damper nuts. You could probably buy the electric one for what it might cost to rent one.
