TEV: What is wrong with Royal Purple gear oil? I just bought a load of it to use when I put my new covers on....

Wayyyyyyyy overkill. You can pound on any after market differential cover for a lifetime and still not need that kind of protection. If you hit something hard enough you may here some disturbing sounds, but I guarantee you that the damage will not be to the diff. Run something like a 37" tire and maybe you'll be hearing your housing bend after some air time.

As Piginajeep said, you will need adjust upper rear control arms to do this and it is needed to be done if you have an aftermarket double cardin u-joint style drive shaft. Click on the link below and see step #64 to see how to do this:

Why not change factory diff fluid this quick?

I can guess why you'd change the fluid after installing new gears, but what is it about the factory gears that the Maint. Schedule doesn't list it until 15K miles? Should I have done it then?

Honestly, I've always wondered that as well but in answer to your question, yes, I would change out your diff fluid at the recommended 15k.
