1995 GMC Yukon GT manual - Front/Rear Diff Fluid change

[Neil Gandhi]

I want to drain and replace the front/rear differential fluid in my 1995 GMC Yukon GT. I plan to use Lucas 75w-90 Synthetic Gear Oil for the front diff and ACDelco GM Original Equipment 10-4051 GL-5 80W-90 Axle Gear Oil for the rear diff with a FEL-PRO RDS55028-1 gasket.

I would just like to confirm that those are the correct fluids for the necessary jobs?
