I use 75W90 synthetic hypoid gear oil (actually quite unlikely you would find an 80W90 or 75W90 that is not a hypoid oil, if it is for the rear axle of any pickup truck, it is a hypoid oil).
You may also find after changing your front axle gear oil that you have a creaking noise when you take corners if you have the Honda limted slip front axle as I do. To stop this, just add a very little bit of limited slip additive which you can purchase from any GM or Dodge dealer. In a GM limited slip axle, you use a small 8oz bottle for approx. 2.5 quarts or liters of axle fluid, and I think the Honda front end only holds about 300ml or a third of a quart. So you would only need an ounce of additive.
