Alright, I started cleaning it off some and looking at it. I think that the truck is 'unloading' on the front wheels and they are not spinning. I can hold one front tire and the front driveshaft and thurn the other tire separate. It feels like there's no gears left in the front diff with when I turn the front right tire and it catches some with the front left tire but also slips a lot. It feels like it blew the front diff?

Is that how it would feel if the front pinion had moved back?

Thanks guys
