the half shafts are in the rear of the car. the power comes from the engint thru the transmisssion thru the driveshaft in the center of the car running from front to rear and into the differential. in the differential the speed is reduced by the ring and pinion gear and turned 90 degrees and sent toward each wheel. the half shafts are shafts that are about 1" in diameter running from the differential to each rear wheel. they will have a rubber boot at each end that expands to about 3" and covers the cv joints which allow the power to be transmitted flexibly while the rear wheels move up and down.

you might want to invest in a good repair manual. i recommend a haynes.

good luck
