Size of spindle nut?

I am going to replace hub this weekend or next and need to know what size the nut is...I believe it is a 35mm but have access to a 36mm socket...just need to know...thanks in advance

Year, 2WD or 4WD would be helpful. If you're referring to the axle nut on 4WD, it's 36mm. (2WD uses a spindle nut, 4WD uses an axle nut.)
