A Front Drive Shaft driveshaft is responsible for transferring engine power from the tranny to the differential and onto the travel wheels. A driveshaft could be a couple of pieces with a centre support bearing in the centre. There will be universal joints at either end of the driveshaft which become flex joints that allow the differential to move upward when the car contacts a bump. A entrance driveshaft yoke is employed to hook up to the transmitting while a rear driveshaft flange is utilized to connect to the differential. On older models the trunk U joint bolts right to the differential without using a rear flange. On entrance wheel drive automobiles there are two drive shafts which are called CV axles.
Driveshaft themselves have hardly any issues with the exception to become bent if they come in contact with an obstruction. Alternatively the U joints can cause complications which are part of the driveshaft such as chirping and clucking when the automobile is moving or placed into gear.
Something you have to know that may not be considered is whenever a driveshaft is taken off the car will no longer be in park. The car will roll for the reason that link between the drive wheels and transmission is removed. You will have to raise the car up using a flooring jack and jackstays. Use protective eyewear and gloves before you begin.
Mark the driveshaft orientation before you begin. This will help returning the driveshaft to its initial placement on the differential that may help avoid driveline vibrations once the driveshaft is reinstalled.
Utilizing a plastic hammer lightly shock the driveshaft loose right from the differential flange by striking the rear yoke (U joint mount). At this point the back 1 / 2 of the shaft will always be free so keep hold of it. On some vehicles you will have a centre support which must be undone by removing the two center support mounting bolts. When removing an older vehicle drive shaft work with electric tape to wrap around the u joint cups therefore they don’t really fall off and release the cup needle bearings.

On front wheel drive cars the driveshaft isn’t used. The tranny and differential is put together 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 correct lubricant. All shafts will be straightened and pc balanced and analyzed to closer tolerances than OEM technical specs.
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.
