Can I drive my 4x4 without the driveshaft to the FWD?

(1991 Chevrolet S10 Blazer)
I want to remove the drive shaft to the front differential to improve my gas mileage. Can I drive the vehicle without any damage to the transmission, transfer case or differential?

Yes you can. But your MPG gains will be so little (if any!), its not really worth the trouble. The parasitic drag on the driveline comes from the transfer case itself. The front axle and driveshaft are being propelled by the front tires rolling. If your vehicle was on a lift (or jacked up with the front wheels off the ground), the front driveshaft and wheels are easily turned by hand and you would realize that they are not detrimental to MPG.
