That's very interesting, 69FBCuda. I did check out Nitto's website, but it appeared that they offer only 8.0" and 9.5" - wide 16.5" radials, but not an 8.75"-sidewall tire, like my truck takes. I wouldn't want to use the narrower tire on the rear of a dually, and I wonder if the wider tire would fit properly. Thanks for the information.
Yes, the diff fluid was a little low, and it was fun replacing that axle seal. Those D300 rear brake drums are really heavy. Also, you gotta know the "firm rap" routine on the outer edge of the axle flange with a ball peen hammer in order to free the end locating cones.
Most parts stores will try to sell you Dana 60 seals and gaskets for a D300, even though you tell them you have the Dana 70 diff. The 60 and 70 take different axle seals and cover gaskets.
