Hey, I'm going to apologize in advance for these questions, but this is the only forum I really visit and I'm sure a fair bit of you own 1500's. 
I'm planning on changing the front and rear diff fluids and the T-case fluid in my 08 GMC 1500. Dex VI is recommended for the T-case, but I'm unsure of what to put in the diffs. The truck has about 90k miles and as far as I know the fluids have never been changed. I don't want to have seal issues and leaks since I don't have a lot of time to work on my crap lately. If it matters, it's a 14 bolt semi-floater with a G80 in the rear, the front I don't know.
Brands, weights, capacities and any other info would be greatly appreciated. Thank you.
