I was wondering if anyone has ever changed the front ring & pinion on the GMT 800 platform (1999 to 2006 Tahoe, pick-up, Escalade, etc...). I need to install 4.11 in a Tahoe project and was looking for some help. I was considering just swapping the assembly, but they seem to be pricey in the salvage yards $700 - $1250 for a low mileage/recent unit. Any help and/or suggestions will be much appreciated. Chuck
