Newbie bought an Xterra for daughter

Hello everyone, I recently bought a 2007 Xterra for my daughter to get around while she goes to college. It has a few issues to sort out but the main thing I'm dealing with is the front drive shaft needs the two universal joints replaced. The Xterra is 4x4. My question is it possible to remove the front drive shaft to get repaired while my daughter drives the vehicle. I know she can't engage 4x4 without the front drive shaft, but is it really needed to drive around in a normal manner?
