Hi and welcome to the site! Be sure to stop by the welcome wagon forum and introduce yourself and yell us a bit about your truck!

I am not sure on front hubs that big of a truck, on all my jeeps and my Suburban (all 1/2 ton axles though) you greased everything to keep it lubed but there was no gear oil in it.

I am sure someone will come along that is familiar with your model and year of truck.
