So i finally found my problem! after checking grub screws, drive shafts, differentials and everything i possibly could and not finding a problem i sat down and thought "things dont just not work like that. theres a reason somewhere." i took off the rims, and took off the rim hub, the inside of my rim hub was completely stripped out, so the pin that was there would just spin, without giving power at all, rendering the rear end powerless just thought id update incase someone runs into a similar situation!
