if you have a differential temp gauge installed the temp will run a little lower than engine temp it is close in range, but generally a little lower
75W-90 in the rear differential. 80W-90 in the front differential (4x4 models). This is according to the 2007 Chevrolet Suburban owner's manual.
That will vary on the gear your are in and what the rear axle gear ratio is.

I purchased my Toro weedeater in 2007. It uses a 50:1 gas/oil ratio.
it is underneath the battery on driver side on top the differential.
IMO, Ratio depends on the carb jetting and oil quality. Try 32:1 (gas:oil) using good synthetic or syn-blend then jet the carb. With stock jetting that should be in the ballpark. Higher altitudes will require leaner jetting (smaller jet size not different gas:oil ratio).
