Driveshaft?

Hello, I'm Danny.

To answer your question, no you can't drive your vehicle with without the front driveshaft. Due to the fact that where the driveshaft connects into the transfer case it is a slip-joint style and you would have all the transfer case oil escape and thereby leave the transfer case to have no lubrication and cause damage, break, or fail. The best thig to do is see if the u-joints need to be replaced to fix the problem completely. Usually when u-joints are worn they will start to make a 'clunk' noise. Here is a tutorial showing how u-joints work:
