If you will not spend your repair money you could stay there a day or two and drive around a few miles and see if the noise stops. If you have metal on metal at the front bearing it might not last long. Typically for a while the sound is much worse than real damage. Once you see the AFT leak rate means you can drive for a while without getting seriously low it would be best not to stop and be shifting gears so the front shaft will tend to stay centered better with everything spinning.
If I was going to make a run for home I would start early one morning to lessen your chance of being stranded at night. Do you have someone at home with a truck heavy enough to tow you back if you broke down going back if you dropped the drive shaft. Tow bills do NOT got towards the repair bill. :(
