With a wrench....LOL

Maybe I'm not understanding the question, but a Mustang driveshaft has four bolts, like most rear wheel drive cars, at the rear u-joint. After you chock the car, so it doesn't roll, you unbolt the four bolts, bump the driveshaft forward a little to let it clear the differential, drop it down and pull it out of the rear of the transmission.

Happy New Year !!!
