G80 Replacement and Diff Size
Two questions concerning my '08 AWD Denali:
1. What is the typical replacement unit for the G80 now that has good reviews?
2. What size is the front and rear differential on the 2008 AWD Sierra Denali's?

I beleive they are 10 bolts in the rear 8.5 /8.625 classification
Front would be 8.25 and FWI front gears are different from rear gears
See bottom of the chart for GM rear axle I.D.
