A driveshaft is accountable for transferring engine power from the tranny to the differential and onto the travel 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 car contacts a bump. A entrance driveshaft yoke is employed to connect to the transmission while a rear driveshaft flange can be used to hook up to the differential. On old models the rear U joint bolts right to the differential without by using a rear flange. On front side wheel drive automobiles there are two drive shafts which are named CV axles.
Driveshaft themselves have hardly any issues with the exception to become bent if they are exposed to an obstruction. However the U joints could cause concerns which are a part of the driveshaft such as for example chirping and clucking when the automobile is moving or put into gear.
Something you need to understand that might not exactly be considered is when a driveshaft is taken off the car will no longer be in park. The automobile will roll as the link between the drive wheels and transmitting is taken off. You will need to raise the car or truck up using a flooring jack and jackstays. Dress in protective eyewear and gloves before starting.
Tag the driveshaft orientation before beginning. This will help come back the driveshaft to its first position on the differential which can help avoid driveline vibrations after the driveshaft is reinstalled.
Utilizing a plastic hammer gently shock the driveshaft loose right from the differential flange simply by striking the trunk yoke (U joint mount). At this point the back 50 percent of the shaft will be free so hang onto it. On some vehicles you will see a middle support which should be undone by taking out the two middle support mounting bolts. When removing a mature vehicle drive shaft use 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 fresh universal joints and CV centering kits with grease fittings and are then completely greased with the proper lubricant. All shafts will be straightened and computer balanced and Front Drive Shaft analyzed to closer tolerances than OEM specifications.
The drive shaft is the part on the lower right side of the picture. The various other end of it might be linked to the transmission.
