hello all, newbie with first post. rear diff broke spider gears. researching the forum it seems there is barely any info on rebuilding the G80. seems most people are replacing the G80 with something different. searching around the forum I think I'm going to call Rons machining and Randys ring&pinion. any advice from anybody who's has attempted swap/upgraded would be appreciated. also any other brands that people are happy with would love to here what was used. 07 Tahoe is just our daily driver/road trip truck so I'm not looking for anything crazy just hoping to do this once. Thanks for any advice!!
