A driveshaft is responsible for transferring engine electricity from the transmission to the differential and onto the drive wheels. A driveshaft can be one or two pieces with a middle support bearing in the centre. There are universal joints at either end of the driveshaft which become flex joints that permit the differential to go upward when the automobile contacts a bump. A front driveshaft yoke is utilized to hook up to the tranny while a backside driveshaft flange is used to connect to the differential. On elderly models the trunk U joint bolts directly to the differential without by using a rear flange. On the front wheel drive autos there are two travel shafts which are known as CV axles.
Driveshaft themselves have hardly any issues with the exception to become bent if they are exposed to an obstruction. On the other hand the U joints can cause complications which are part of the driveshaft such as chirping and clucking when the car is moving or put into gear.
Something you have to know that may well not be thought of is whenever a driveshaft is removed the car will no longer maintain park. The car will roll since the link between your drive wheels and tranny is taken out. You need to raise the car up using a ground jack and jackstays. Have on protective eyewear and gloves before you begin.
Mark the driveshaft orientation before you begin. This will help give back the driveshaft to its original situation on the differential that may support avoid driveline vibrations once the driveshaft is reinstalled.
Using a plastic hammer smoothly shock the driveshaft loose by the differential flange simply by striking the rear yoke (U joint install). At this time the back one half of the shaft will end up being free so keep hold of it. On some autos you will have a center 
support which must be undone by the removal of the two centre support installation bolts. When removing an older vehicle drive shaft employ electrical tape to wrap around the u joint cups hence they don’t really fall off and discharge the glass needle bearings.
On front wheel travel cars the driveshaft is not used. The transmission and differential is blended into one unit called a transaxle.
All shafts are Front Drive Shaft reassembled with new universal joints and CV centering kits with grease fittings and so are then completely greased with the proper lubricant. All shafts are straightened and pc balanced and examined to closer tolerances than OEM requirements.
The drive shaft may be the part on the low proper side of the picture. The additional end of it would be connected to the transmission.
