good evening my name is ***** ***** I will assist
check and see if the rear drive shaft is turning when you put it in gear.
does the speedometer work when it wont move
does not have to be on jack stands. if the differential is a issue, then the shaft may turn and the truck will not move.
it does sound like the transfer case is an issue here
why has it sat so long
and the tansfer case grinds when shifting???
I did read it more than once. none of it makes sense. if it grinds as you say, the trans is turning it internally.
once again why did it sit so long???
