Drive/Propeller Shaft: Description and Operation
Driveshaft
NOTE: All driveshafts are balanced. If undercoating the vehicle, protect the driveshaft and U-joints to prevent overspray of any undercoating material.
Vehicles have the following types of driveshafts:
-
Front driveshaft with CV joints at the front and rear. The front driveshafts are not serviced
-
One-piece rear driveshafts with a front and a rear U-joint flange
-
Two-piece rear driveshafts with a front U-joint, center bearing with a slip joint and a flanged U-joint at the rear
Driveshafts are used to transfer movement from the transmission or transfer case to the front or rear axle. The driveshaft is composed of the U-joints, CV
joints, connecting shafts and the attaching yokes. Some vehicles are equipped with a center support bearing. The center support bearing is prelubricated
and sealed for the life of the bearing.
Driveshafts differ in length, diameter and type of yoke to accommodate various wheelbase and powertrain combinations.
