A driveshaft is a tube or pair of tubes that transmits power between the transmission and
Differential, with universal joints located at either end and in the center of two-piece driveshafts. Single piece driveshafts have a splined yoke at the front that allows for movement during vehicle operation, while two-piece driveshafts have a slip joint on the front of the rear section and a center support bearing. The driveshaft assembly requires little service, with universal joints lubricated for life and replaced if problems arise. Inspection involves checking for dents, cracks, and oil leakage, as well as ensuring proper operation of universal joints and center bearings. Driveshaft mounting bolts should also be checked for tightness, and similar checks should be performed on the front driveshaft and driveaxles of 4WD models. Noise or vibration while driving may indicate problems with the driveshaft or other components.
