What would happen........

What would happen if u take out the drive shaft on a awd dsm and drive around without it,or can u drive around with blown rear axles what will happen if u do this?

You would just burn up the vicious coupling and surely gall the gears in the center diff.

No, you cannot do this. Unless you have a welded center differential or spool in the center differential things will be damaged. If you do not know what center differential you have, there is a way to tell (ask if you want an explanation.)

I would not drive with "blown" rear axles either. What is (possibly) "blown" about them?? Are they broken in half, or clicking, or missing parts, or locked up, or bent (), or what??

Finally to address your question exactly, I have to make a presumption. I'll presume that you have a factory viscous coupling in your center differential. What would happen with the driveshaft out: Your transfer case would have to free wheel with little to no lubricant (you did not mention that you wished this removed, and with the driveshaft removed the oil will leak out). As you attempt to put power through the drivetrain to the wheels by engaging the clutch, the viscous coupling in the center differential will attempt to balance the power between the front and rear axles. The transmission-to-transfer case shaft is connected to half of the viscous coupling, while the front differential is connected to the other half of the center viscous coupling. When the load on the front axles and rear axles is the same the two halves of the center viscous coupling are stationary with respect to each other. When the load is decreased on one side of the center viscous coupling (the trans-to-tcase) that side of the viscous coupling spins faster than the loaded side. The viscous fluid between the two sides (which are a series of plates that spin near each other(like a clutch pack)) is moved around and has friction between the two sides. The friction causes heat which partially solidifies the fluid, making it more difficult for the lighter load axle to spin faster. When this situation continues for an extended period of time, so much heat is generated that the center viscous coupling cannot withstand failure.
Lastly while the vehicle is moving/being driven in this state the rear differential (ring and pinion) will be driven by the rear wheels through the rear halfshafts. I do not believe there is any detriment to this, unless something is broken/damaged in that part of the drivetrain.

Good luck,

Cool cause people were saying that u can remove the driveshaft and it will be a fwd turbo with no problem.so lets say u your rear axles break on a launch and u got no power to the rear wheels how long can u drive like that and is there any damage that will occur over long periods of time?

When u learn to punctuate and spell, please come back.
