A Front Drive Shaft driveshaft is accountable for transferring engine electricity from the transmitting to the differential and onto the drive wheels. A driveshaft could be one or two pieces with a centre support bearing in the middle. There happen to be universal joints at either end of the driveshaft which act as flex joints that allow the differential to move upward when the automobile contacts a bump. A front side driveshaft yoke is employed to connect to the tranny while a backside driveshaft flange can be used to hook up to the differential. On old models the trunk U joint bolts right to the differential without by using a rear flange. On the front wheel drive vehicles there are two drive shafts which are named 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 could cause challenges which are a part of the driveshaft such as chirping and clucking when the car is moving or placed into gear.
Something you should know that might not be thought of is whenever a driveshaft is eliminated the car will no longer maintain park. The car will roll since the link between the drive wheels and transmitting is eliminated. You need to raise the car up using a ground jack and jackstays. Use protective eyewear and gloves before starting.
Tag the driveshaft orientation before beginning. This will help returning the driveshaft to its classic situation on the differential which can help avoid driveline vibrations once the driveshaft is reinstalled.
Utilizing a plastic hammer smoothly shock the driveshaft loose coming from the differential flange simply by striking the rear yoke (U joint install). At this point the back 1 / 2 of the shaft will end up being free so keep hold of it. On some vehicles you will see a centre support which should be undone by removing the two centre support installation bolts. When removing an older vehicle drive shaft use electrical tape to wrap around the u joint cups and so they don’t really fall off and relieve the cup needle bearings.
On front wheel drive cars the driveshaft is not used. The tranny and differential is combined into one device 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 correct lubricant. All shafts will be straightened and computer balanced and analyzed to closer tolerances than OEM features.
The drive shaft may be the part on the low right side of the picture. The other end of it might be linked to the transmission.
