2002 Fourtrax ES350 4WD stopped working

So today after I finally motivated myself to take out and clean the carb (was clogged with dirt), now motor runs like a dream.
Decided to take her out for a spin, while climbing the driveway back I head a strange metallic click from under the machine and realized she is not going forward as eagerly and that rear is spinning out. I was able to estabilish that front shaft still spins. Is my front diff toast?
Thanks
