One additional note. There is a brake line running across the axle, jumping up at the diff. Make sure it is up and out of the way. When I put my 265/75R16 spare up in the well (admittedly with a rear hitch on the truck), the tire rubs the back of the diff. It managed to grab that line and rub it up and down the diff cover for a while before I noticed it (fortunately before it wore through the line).
I seem to remember pulling the line up above the diff pumpkin and using a couple of zip ties to hold it up out of harms way.
