can I run a awd front diff out 04 yukon denali with a push button transfer case or should I just go with a regular front diff? reason i ask because I have both and want to run a 4l80e and push button since its easier to find a 32 spine

 

You will need to run a 4x4 front diff. It has an actuator to engage the front diff. The AWD front diff doesn't have this and the front will always be locked.
