the driveshaft is the tube that runs from the rear of the transmission or transfer case if it has 4x4 and runs to the rear axle.
The rubber hose that connects from the chasis to rear axle is for grip.
Universal Joints connect the Driveshaft between the Transmission and the Rear Axle Differencial that transfers power from the Engine to the Transmission to the Rear Axle to move the car.
The rear differential is where the driveshaft meets the axle. Its right in the middle of the axle and is about the size of a basketball.
The number of times the driveshaft turns for each turn of the rear end gear. For example, a 3.55 rear end gear would turn once for every 3.55 rotations of the driveshaft.
It depends if it is a 4 wheel drive truck. A rear driveshaft is used to drive the rear axle. A front driveshaft is used to drive the front axle on a 4X4.
Look underneath the rear fo the vehicle. If you see a driveshaft extending back from the area of the engine to a rear axle and differential housing for the rear wheels, you can be sure that it is an AWD model. 2WD models will lack the driveshaft, the axle, and the differential housing.
On the rear wheels, it's the axle.

The vehicle needs to be raised and supported by the frame. The u joint at the rear of the driveshaft needs to be removed, as well as the brake lines and abs connections. the rear axle assembly can then be unbolted from the springs and removed.
Between rear wheels. it is the rear axle housing. The diff is usually the round object in center that driveshaft attaches to with gears inside.
