A driveshaft is accountable for transferring engine electric power from the transmitting to the differential and onto the drive wheels. A driveshaft can be one or two pieces with a center support bearing in the centre. There happen to be 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 used to connect to the transmission while a back driveshaft Front Drive Shaft flange is employed to hook up to the differential. On more mature models the rear U joint bolts directly to the differential without utilizing a rear flange. On front wheel drive cars there are two drive shafts which are known as CV axles.
Driveshaft themselves have hardly any problems with the exception to become bent if they are exposed to an obstruction. On the other hand the U joints can cause challenges which are a part of the driveshaft such as for example chirping and clucking when the car is moving or placed into gear.
Something you need to understand that might not be considered is when a driveshaft is removed the car will no longer be in park. The automobile will roll because the link between the drive wheels and tranny is taken out. You need to raise the car or truck up using a floor jack and jackstays. Use protective eyewear and gloves before you begin.
Indicate the driveshaft orientation before beginning. This will help return the driveshaft to its first situation on the differential which can help avoid driveline vibrations after the driveshaft is reinstalled.
Utilizing a plastic hammer delicately shock the driveshaft loose coming from the differential flange by striking the rear yoke (U joint mount). At this point the back half of the shaft will be free so hang onto it. On some automobiles there will be a center support which must be undone by eliminating the two center support mounting bolts. When removing a mature vehicle drive shaft use electric tape to wrap around the u joint cups consequently they don’t fall off and release the glass needle bearings.

On front wheel travel cars the driveshaft is not used. The transmission and differential is combined into one device called a transaxle.

All shafts are reassembled with fresh universal joints and CV centering kits with grease fittings and so are then completely greased with the proper lubricant. All shafts will be straightened and pc balanced and tested to closer tolerances than OEM requirements.
The drive shaft may be the part on the lower right side of the picture. The various other end of it would be connected to the transmission.
