Front driveshaft/ noise now

[Rod M]

Hello everyone, new to site so not sure how to do this properly. I bought a 2002 Yukon Denali the front driveshaft was removed so I put back in, there is no clunking but it grinds on hard acceleration from a stop? It sounds like a spline trying to mesh up? Has anyone had this happen? Is it the transfer case cause it shouldn’t have been driven without the shaft? It drives without it but want front shaft back in

was the spline shafts greased up good before re installing it?
