An automotive differential assembly for a vehicle having a driving case enclosing a pair of driving members operably coupled with a pair of driven members. The driven members are secured to output shafts and the driving members are forcibly driven by a driving shaft having its opposite ends in engagement with the driving case. The driving shaft passes through eccentric or angled apertures formed by cooperating arcuate surfaces provided in opposing surfaces of the driving members. The driving members and the driven members are urged together respectively by at least four dampening springs providing both axial and radial force which dampens or eliminates sudden impact encountered when the shaft moves back and forth within the apertures. The driving members may be loosely aligned and interrelated by pins and enlarged holes, by pins and laterally opened holes or by a key and keyway or channel construction.
