Hello new here Needing help would really appreciate some feedback! I have a 2001 tahoe with the push button 4x4. Front diff has gone or needs at least a complete rebuild. I have a front diff from a 02 escalade same 373 gears as my tahoes diff pretty sure that means its an awd unit though. The number on caddy diff is 30004022 stickers are washed off. Anyone know if it would be possible to use the awd diff and what mods if any?
