A GL-5 rated 80w90 should be fine for open diff gears. IMO. You can buy the 75w90 as well, a little extra insurance.
Don't buy the store brand ........ eek

I just changed the rear diff fluid on an 04 Tahoe, used Valvoline 75w90. They make some hi-tech fluids now that are more expensive, and if I didn't have 200,000 miles on the vehicle, I may of went with one of them brands.

Do you have your owner manual lister? I'd stick with the manufacturer's recommendation myself.

Oh, nothing wrong with asking. Ask away! I just think they are handy to have.
