Generally speaking Ditrworx, TBN members like to have a bit more detail - like what clunked or what was specifically happening when this unfortunate situation arose.
There is a wealth of knowledge here if the query is framed. For instance I have a B21 and it has served me well, and like all mechanical things I listen to the sound of the machine to gauge its well being usually.
So for your case the front wheels are no longer moving in FWD, and you have a noise from the front axle, thus something is either loose (best case) or you have sheared a gear in the front axle (s).
There is a shield that covers the front axle shaft, which if loose will bang about but not impede the FWD, of course this is a simple fix.
If you have drive in one but not two sides then you can narrow this down to L/R if not in both then its the center gear and work back / forward from there,
Its not real difficult to raise the front end with the loader and start removing/isolating the issue then pullling the front end apart.
So a bit more info is appreciated

Sadly i dont have much to offer. I just bought it like this. The driveshaft spins but no power to either wheel. The sound i hear is in the input side of the axle but it has no visible differential so i am uncertain how to tear it down

Here is a picture of the front drive shaft. If this one is turning then its in the front axle drive assembly.
Lift the front end with your loader and block it up behind the front end (if you intend to leave it like this for a while) then try turning the wheels by hand and see what happens.
You can find a PDF version of the manual on line but if you PM me your email I will send to you,
