Multiple Choice

Two components that allow the necessary movement of the drive shaft are:

The thing being tested is how a drive shaft stays able to transmit power while the vehicle moves and wheels travel up and down. To do that, you need parts that both bend and extend the shaft. The universal joint provides the bending capability, allowing the driveshaft to transmit torque even as the angle between components changes. The slip yoke gives a sliding, telescoping connection so the shaft can lengthen or shorten as suspension moves or drivetrain components shift. Together, they let the drive shaft accommodate both angular and length changes. Bearings and seals mainly support and seal the shaft as it rotates; they don’t allow the shaft to bend or slide. A CV joint and axle describe a different drive arrangement and don’t specifically address the two-way movement the shaft needs. Wheel hub and bearing support wheel rotation, not the drive shaft’s articulation.
