A driveshaft is in charge of transferring engine electric power from the tranny to the differential and onto the travel wheels. A driveshaft could be one or two pieces with a center support bearing in 
the centre. There will be universal joints at either end of the driveshaft which become flex joints that permit the differential to move upward when the automobile contacts a bump. A the front driveshaft yoke is utilized to hook up to the transmitting while a rear driveshaft flange is used to hook up to the differential. On older models the trunk U joint bolts right to the differential without using a rear flange. On front side wheel drive automobiles there are two drive shafts which are known as CV axles.
Driveshaft themselves have very little problems with the Front Drive Shaft exception to become bent if they come in contact with an obstruction. Alternatively the U joints can cause concerns which are a part of the driveshaft such as for example chirping and clucking when the car is moving or put into gear.
Something you need to know that might not be thought of is whenever a driveshaft is taken away the car will no longer be in park. The car will roll as the link between your drive wheels and transmitting is taken out. You will have to raise the car or truck up using a floor jack and jackstays. Have on protective eyewear and gloves before starting.
Tag the driveshaft orientation before beginning. This will help return the driveshaft to its original position on the differential which can support avoid driveline vibrations after the driveshaft is reinstalled.
Using a plastic hammer lightly shock the driveshaft loose right from the differential flange simply by striking the rear yoke (U joint mount). At this point the back one half of the shaft will become free so hang onto it. On some automobiles you will see a center support which should be undone by getting rid of the two center support mounting bolts. When removing an older vehicle drive shaft employ electrical tape to wrap around the u joint cups so they don’t really fall off and relieve the cup needle bearings.
On front wheel travel cars the driveshaft is not used. The transmission and differential is merged into one product called a transaxle.
All shafts are 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 features.
The drive shaft may be the part on the low right side of the picture. The various other end of it might be linked to the transmission.
